Answer:
Step-by-step explanation:
Convert 6 feet to inches 6(12) = 72
convert 71/2 feed to inches 7.5(12) = 90
90 - 18 = 72
18 inches.
They are vertical angles so you need to make the following equal
7y=5y+36 and 3x-21=2x+4
Solve for y and then x
7y=5y+36
Subtract 5y on both sides to get
2y=36
Then divide by 2 on both sides to Get y=18
For 3x-21=2x+4,
Subtract 2x on both sides to obtain
x-21=4
Then add 21 to both sides to get
x=25
Hope this helps!! Mark as brainliest!!!
Answer:
Step-by-step explanation:
Draw the altitude from the vertex angle to the base. You have two congruent, right triangles. The hypotenuse of each triangle is
√[(56/2)²+45²] = √[28²+45²] = √2809 = 53 mm
perimeter of larger triangle = 2×53 + 56 = 162 mm
