Skylar drew two triangles that share a side and labeled the two portions of the base w and x. Then he solved for w and x as shown. Are his calculations correct? Explain in full sentences. (5 points)
Answers
The two triangles he drew and also the calculations he did are missing, so i have attached them.
Answer:
His calculations are not correct
Step-by-step explanation:
From the attached image showing the triangle, we can see that for the smaller triangle with w, 5.5 and 45° angle, it is clear that;
Opposite side is 5.5
Adjacent side is w
And angle is 45°.
Hypotenuse is unknown
Thus, from trigonometric ratios;
Opposite/adjacent = tan (angle)
Thus;
5.5/w = tan 45°
In Skylar's calculation, he expressed it as; 5.5/w = sin 45°
Therefore, his calculation is wrong.
Secondly, for the bigger triangle, it is clear that;
Opposite side is 5.5
Adjacent side is w + x
And angle is 35°.
Hypotenuse is unknown
Thus;
5.5/(w + x) = tan 35°
Whereas,skylar expressed his own as;
5.5/(w + x) = sin 35°
Again his calculation is wrong.

The length of a rectangle is (3x - 1) and its width is ( 2x + 5). What is the area of the rectangle?
Answers
Answer:
3x^2 + 13x - 5
Step-by-step explanation:
To find the area, you multiply the length by width. So its is (3x - 1) * (2x + 5)
Then distribute. (3x * 2x) + (3x *5) + (-1 *2x) + (-1 * 5)
So 3x^2 + 15x -2x -5
Final Answer: 3x^2 + 13x - 5

A certain television is advertised as a 10-inch TV (the diagonal length). If the width of
the TV is 6 inches, how many inches tall is the TV?
Answers
Answer:
8 in
Step-by-step explanation:
Given data
DIagonal= 10 in
Width= 6 in
`Height=???
We know that the expression that can be used to find the missing dimension is given as
d^2= w^2+h^2
substitute
10^2=6^2+h^2
100= 36+h^2
100-36= h^2
64= h^2
h= √64
h= 8 in
Hence the height is 8 in
pam is 17 years old and her sister is 9. her two brothers are 11 and 7 years old. what is the mean of their ages
Answers
Answer:
11
Step-by-step explanation:
17+9+11+7 divided by 4
because the mean= sum of the terms divided by the number of terms
the sum= 17+9+11+7=44
the number of terms= 4
44 divided by 4= 11
Answer:
(17+9+11+7) / 4 mean is an average
it is equal to the sum of the elements divided by the number of elements
the sum is 44
the number of elements is 4
the mean is the average= 44/4=11

An angle measures 27.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answers
Answer:
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees.
a+a-27.2=180
2a-27.2=180
2a=207.2
a=103.6, and since b=a-27.2
b=76.4
So one angle is 103.6 degrees and the other is 76.4 degrees.
