Answer:
A
Step-by-step explanation:
The base angles of an isosceles triangle are congruent
The sum of the 3 angles in a triangle = 180°, hence
180° - 112° = 68°
base angle = = 34°
Thus each base angle equals 34° → A
7^-1/7^-2
7^(-1+2)=7^1=7

you now aswer to that question yes or no
First Problem:
1/2 * -2 2/5 = 1/2 * -12/5 = -12/10
Simplify -12/10 into -6/5
