Question

ZA and ZB are complementary angles. If m_A= (7x + 28)° and m

Answer 1

Answer:

mA=56 degrees

Step-by-step explanation:

Complementary angles adds up to 90 degrees. This imply that

$(7x+28)+(8x+2)=90$

From this equation, we can find x:

$15x+30=90\\15x=90-30\\15x=60\\x=\frac{60}{15}\\x= 4$

Now, we can substitute the value for x into the angle mA:

$mA=(7*4+28)\\mA=(28+28)\\mA=56$
