Find the missing angle in the triangle.
Question 1 options:
A. 90°
B. 25°
C. 108°
D. 130°
Answer:
A. 90 degrees
Step-by-step explanation:
a triangle has a total of 180 degrees in all of its angles combined (excluding the outside angles).
61+29=90
180-90=90
Grace drew a triangle. Its sides were 6 mm. 7 mm and 11 mm.
It has one obtuse and two acute angles.
Complete the sentence to describe the triangle Grace drew.
Answer:
That would be an obtuse-scalene triangle.
Step-by-step explanation:
It is scalene because none of the sides are congruent. This means that none of the angles or sides are the same.
A cereal box says that now it contains 40% more. Originally, it came with 24 ounces of cereal. How much cereal does the box come with now?
Answer:
36 oz
Step-by-step explanation:

Angles α and β are angles in standard position such that: α terminates in Quadrant I and sinα = 3/5 β terminates in Quadrant III and tanβ = 5/12 . Find sin(α - β).
Answer:
-16/65
Step-by-step explanation:
Given sinα = 3/5 in quadrant 1;
Since sinα = opp/hyp
opp = 3
hyp = 5
adj^2 = hyp^2 - opp^2
adj^2 = 5^2 = 3^2
adj^2 = 25-9
adj^2 = 16
adj = 4
Since all the trig identity are positive in Quadrant 1, hence;
cosα = adj/hyp = 4/5
Similarly, if tanβ = 5/12 in Quadrant III,
According to trig identity
tan theta = opp/adj
opp = 5
adj = 12
hyp^2 = opp^2+adj^2
hyp^2 = 5^2+12^2
hyp^2 = 25+144
hyp^2 = 169
hyp = 13
Since only tan is positive in Quadrant III, then;
sinβ = -5/13
cosβ = -12/13
Get the required expression;
sin(α - β) = sinαcosβ - cosαsinβ
Substitute the given values
sin(α - β) = 3/5(-12/13) - 4/5(-5/13)
sin(α - β)= -36/65 + 20/65
sin(α - β) = -16/65
Hence the value of sin(α - β) is -16/65

Write all three forms (slope intercept, point slope and standard) of a line containing the points (4, -11/3) and (1/2, -29/6).
Answer:
See explanations below
Step-by-step explanation:
Slope intercept form of the equation is expressed as y = mx+b
m is the slope
b is the intercept
Given the coordinates (4, -11/3) and (1/2, -29/6)
Slope m = -29/6-(-11/3)÷(1/2-4)
m = (-29/6+11/3)÷(-7/2)
m = -29+22/6÷(-7/2)
m = -7/6÷(-7/2)
m = -7/6×2/-7
m = 2/6
m = 1/3
Get the intercept b
Substitute m= 1/3 and (4, -11/3) into y = MX+b
-11/3 = 1/3(4)+b
-11/3 = 4/3+b
b= -11/3-4/3
b= -15/3
b =-5
Get the required equation
y = 1/3 x -5 (slope-intercept form)
Point slope form of the equation is expressed as y-y0 = m(x-x0)
Substituting m = 1/3 and the point (4,-11/3)
x0 = 4
y0 = -11/3
y - (-11/3) = 1/3(x-4)
y+11/3 = 1/3(x-4) (point-slope form)
For standard format
Recall that y = 1/3x - 5
Multiply through by 3
3y = 1/3x(3)-5(3)
3y = x-15
3y-x = -15(standard form)
(-4,-6) perpendicular to the line y=2x+5

I dont know what this is pls help
Answer:
Plane
Step-by-step explanation:
The definition of a Plane is "In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far."
It couldn't be a Ray or a Line Segment because a Ray has 1 end point, and a Line Segment has 2.
It also couldn't be a Line because a Line is only 1 dimensional.
The answer has to be Plane.
For all the values of x,
f(x)=2x^2 and g(x)=x+1
Solve fg(x)=gf(x)
Answer:
if f(g(x)) = g(f(x)), then x is equal to zero.
Step-by-step explanation:
given:
f(x) = 2x²
g(x) = x + 1
then:
f(g(x)) = 2(x + 1)²
g(f(x) = 2x² + 1
so if:
f(g(x)) = g(f(x))
then:
2(x + 1)² = 2x² + 1
2(x² + 2x + 1) = 2x² + 1
2x² + 2x + 1 = 2x² + 1
2x = 0
x = 0

Answer:
y = -5/4x - 7
Step-by-step explanation:
First, find the slope:
3 - -7 / -8 - 0 = -5/4
Put it in point slope form:
y + 7 = -5/4(x-0)
y + 7 = -5/4x
y = -5/4x - 7
