Question

If angle A = 7° + 4x and angle B = x + 23°, which is a
A and angle B are complementary angles.
true statement ?

$7 + 4x + x + 23 = 90 \\ 30 + 5x = 90 \\ 5x = 90 - 30 \\ 5x = 60 \\ x = 60 \div 5 \\ x = 12$
$7 + 4x \\ 7 + 4 \times 12 \\ 7 + 48 \\ 55$
$x + 23 \\ 12 + 23 \\ 35$
​

Answer 1

Answer:

tex]7 + 4x + x + 23 = 90 \\ 30 + 5x = 90 \\ 5x = 90 - 30 \\ 5x = 60 \\ x = 60 \div 5 \\ x = 12 \\ [/tex]

$7 + 4x \\ 7 + 4 \times 12 \\ 7 + 48 \\ 55$

$x + 23 \\ 12 + 23 \\ 35$
