Answer:
D. 1 : 1
Step-by-step explanation:
The ratio of the two legs in any isosceles triangle is 1 : 1. That is also true of this isosceles right triangle. (You can tell it is isosceles because the acute angles are identical in size.)
Answer:
d = 36°
Step-by-step explanation:
If ∠1 ≅ ∠2, thia means both angles are the same.
Given m∠1 = 3d + 2 and m∠KHG = 70
Substitute m∠KHG = 70 = m<1 into the expression to get d
m<1 = 180-m∠KHG
m<1 = 180-70
m<1 = 110
110 = 3d+2
subtarct 2 from both sides
110-2 = 3d+2-2
108 = 3d
rearranging
3d = 108
Divided both sides by 3;
3d/3 = 108/3
d = 36°
1.2 times 15 = 18 so your answer will be A
