I think is B
I think is B
a=7/2-3/10
Step-by-step explanation:
20a +158+6c= 120+60+48
20a +158+6c=228
20a =228-158-6c
20a =70-6c
a= 7/2 - 3/10
Answer:
The answer for ∠B = 68°
Step-by-step explanation:
Total angle in a triangle is 180° so you can just substract ∠A and ∠C from 180° :
∠A + ∠B + ∠C = 180°
90° + ∠B + 22° = 180°
∠B = 180° - 90° - 22°
= 68°
The answer is 9m :) good luck!
