Answer:
50.6 cm
Step-by-step explanation:
We can use similar triangles and proportions to solve. Put the smaller triangle side over the larger triangle side.
x 46.2-14 (This is the length of the short side of the triangle)
--------- = -------------
72.6 46.2
Using cross products
46.2 *x = (46.2-14) *72.6
46.2 *x = (32.2) *72.6
46.2 *x = (32.2) *72.6
46.2x =2337.72
Divide each side by 46.2
46.2/46.2 *x = 2337.72/46.2
x = 50.6
Answer:
T(a) =(a+2)/11
Step-by-step explanation:
The inverse of the inverse is the function
To find the inverse let T^-1(a) be y
y = 11a -2
Exchange y and a
a = 11y -2
Solve for y
Add 2 to each side
a+2 = 11y -2 +2
a+2 =11y
Divide each side by 11
(a+2)/11 =y
T(a) =(a+2)/11
So every triangle has to add up to 180° so for 11 you would have to find out 180-84-36 which would be 60 and because there is a right angle (90°) or the little square you do 90-60 and get 30 then you do 180-86-30 getting you to your final answer of 64
