Answer:
m<A = 30
Step-by-step explanation:
The right square is a 90 degree angle
All angles in a triangle add up to 180 so:
x + 37 + x + 67 + 90 = 180
2x + 194 = 180
2x = 180 - 194
2x = -14
x = -7
<A:
x + 37
-7 + 37
30
A=30
Set your equation up as following:
180=90+(x+37)+(x+67)
180=90+37+67+2x
180-90-37-67=2x
-14=2x
-14/2=x
-7=x
Angle A = x+37
A=-7+37
13(4+x)
=52+13x
13 multiplies the 4 and x.
then 13 multiply 4 is 52 while 13 multiply x 13x.
