You have to prove that 2 angles are conguent to the other triangles angles; example: ∠A≅∠C by the additon POC (2 of those) and then one side; example: AB≅BA by the reflexive POE (1 of those)
I cant see the triangles but thats how you do them, also im learning this right now too, look up the triangle congruence things like ASA ≅ SSS≅ HL≅ exc. a chart will explain how to prove them using that:

Ray earns $15 an hour for up to 40 hours a week. If he works more than 40 hours a week, he is paid time and a half. That means Ray is paid 150% of his hourly wage for every hour he works over 40 hours.
How much additional money does Ray earn for every hour he works over 40 hours?
Last week, Ray worked 46 hours. He incorrectly calculated he earned $45 of additional pay. What was Ray’s error when he miscalculated his overtime pay? Explain your answer.
How much was Ray’s paycheck for working 46 hours? Show your work.
Would Ray make more money working 40 hours a week for two weeks or working 32 hours one week and 46 hours the next? Justify your solution.
Answers
For every hour he works over 40 hours, he is paid an additional $7.50.
Ray’s error when he miscalculated his overtime pay is +$45.
How to calculate the error?Suppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
His normal pay is $15/h
150%/100 = 1.5
Multiply his normal pay by the rate in decimal form;
$15 X 1.5 = $22.5
His OT pay is $22.5/h.
Additional money = (OT pay) - (Normal pay)
= $22.5 - $15
= $7.5
Or $7.5 = $7.50
Thus, For every hour he works over 40 hours, he is paid an additional $7.50.
Ray actual pay for the week was $100 then from the question he incorrectly calculated it as {$100 + $45} = $145 which is $45 above his actual pay.
Error = measured value - actual value.
Error = $145 -$100 =$45.
Since the value $145 is greater than his actual pay $100, we have to include a positive sign to the error $45.
Therefore, Error = +$45.

Find the surface area of the 3D solid. Round to one decimal place.
Answers
Answer:
172.5
Step-by-step explanation:
The formula for the surface area of a right circular cone (the following shape) is πr( r + √h^2 + r^2). Since the radius (r) is already given (3) and the height (h) is already given (15), you just replace each r with 3 and h with 15. After solving this out, you should get 172.45, which rounds to 172.5 to the first decimal place

Find the gradients of lines A and B. NEED ASAP
Answers
Step-by-step explanation:
The line A, the slope is +2
And line B the slope is n-1
Answer:
For A;
x1 = -2, y1 = -3, x2 = 3, y2 = 7
Gradient = (y2 - y1)/(x2 - x1)
= (7 - (-3))/(3 - (-2))
= 10/5 = 2.
For B;
x1 = 7, y1 = -2, x2 = -2, y2 = 7
Gradient = (y2 - y1)/(x2 - x1)
= (7 - (-2))/(-2 - 7)
= 9/-9 = -1.

Answers
Answer:
y=-2x+5; slope is -2
Step-by-step explanation:
slope is rise/run. we can see it rises 2 and goes left one which would give us rise/run=2/-1=-2. that is our slope.
using y=mx+b to write the equation, m is slope and b is the y-int.. we can see that the y-int. is (0,5). we can plug 5 into b.
plugging b and m in we can get the equation: y=-2x+5

What is the centroid of the triangle?In science and math, the centroid of a planar figure or firm figure, also known as the point of intersection or center of the figure, is the mean absolute position of all of the other points on the subject's surface.
The centroid of the triangle is given as,
(x, y) = [(x₁ + x₂ + x₃) / 3, (y₁ + y₂ + y₃) / 3]
Use the coordinates J(7, 8), K(1, 2) and L(5, 2) for △JKL. Then the centroid for △JKL is at point M is given as,
(x, y) = [(7 + 1 + 5) / 3, (8 + 2 + 2) / 3]
(x, y) = (13/3, 12/3)
(x, y) = (13/3, 4)
Then the distance between the point JM is calculated as,
D² = (13/3 - 7)² + (4 - 8)²
D² = 7.1111 + 16
D² = 23.11
D = √23.11
D = 4.81 units
The distance between the point JM will be 4.81 units.

tenth of a cubic meter.
Answers
Answer:
Volume of pyramid with square base is 1057.54 m³
Step-by-step explanation:
We are given:
Length of base of pyramid = 14.4 m
Height of pyramid = 15.3 m
We need to find:
Volume of pyramid with square base
The formula used is: [tex]Volume=\frac{1}{3}\times a^2 \times h[/tex]
Where a = base of pyramid and h is height
Putting values and finding volume
[tex]Volume=\frac{1}{3}\times a^2 \times h\\Volume=\frac{1}{3}\times (14.4)^2 \times (15.3)\\Volume=\frac{1}{3}\times 207.36 \times 15.3\\Volume=1057.54 \ m^3[/tex]
