Answer:
Step-by-step explanation:
3x - 13 + 58 = 90. [Complementary Angles]
=> 3x + 45 = 90
=> 3x = 90 - 45
=> 3x = 45
[tex] = > x = \frac{45}{3} [/tex]
=> x = 15 (Ans)
X=15
The Square means the 2 angles = 90 degrees so we do this
90 - 58 = 32
so now we KNOW the second angle has to be 32.
so
3x-13=32
now we solve
+13 +13
3x=45
/3 /3
x=15
Hope I helped :D
