A and B are complementary angles. If A = (x + 9) and m B = (7x – 15)° then find the measure of B.

Marina CMI [18]

Answer:

$coplementary \: angles \: = 90° \\ (x + 9)° + (7x - 15)° = 90° \\ (8x - 6)° = 90° \\ 8x = 90 + 6 \\ 8x = 96° \\ x = 12\\ angle \: B. = ((7 \times 12)- 15) \\ = 69°$

In the diagram, what is the measure of angle 1?

VLD [36.1K]

We know that
angle (3x) and angle (9x) are supplementary angles
so
3x+9x=180°------> 12x=180°------> x=180°/12-----> x=15°

angle (9x) and angle (1) are supplementary angles
so
9x+∡1=180---------> 9*15+∡1=180
∡1=180-9*15---------> ∡1=180-135------> ∡1=45°

the answer is
∡1 is 45°

alternative method
angle 1 = angle 3x----------> vertical angles
∡1=3x-----> 3*15-----> 45°
