Answer:
i got b and h{i hope this helps}
Step-by-step explanation:
The two angles (6x+4) and 32 degrees are complementary angles. They add to 90 degrees. The two angles are adjacent and form a right angle. The right angle marker is the square marker. Two adjacent right angles form a straight angle (180 degrees)
Add up the angles and set the sum equal to 90. Then solve for x
(6x+4) + (32) = 90
6x+4 + 32 = 90
6x+36 = 90
6x+36-36 = 90-36 .... subtract 36 from both sides
6x = 54
6x/6 = 54/6 ... divide both sides by 6
x = 9
Since x = 9, this means that
6x+4 = 6*9+4 = 54+4 = 58
So the missing angle is 58 degrees (note how 58+32 = 90)
Answer:
1. 27.5 in.^2
2. 360 in.^2
Step-by-step explanation:
1.
A = bh/2
A = (4 + 7)(5)/2
A = 27.5 in.^2
2.
A = bh/2
A = (35 + 13)(15)/2
A = 360 in.^2
so for question 2 find the area of the rectangle first:
then you find the area of the triangles:
Add up all the answers:
and for question 3, part A, you just find the area of the 2 boxes and multiply:
so the surface area of the box is 90 square inches therefore the paint covered 90 square inches. For part B, just add up the length of the thick black lines:
How these helped have a good day
E. D. A. I'm not 100% tho
