Question

Pls help me with this!

Answer 1

Answer:

See below.

Step-by-step explanation:

1.

(a) < PMR

(b) < QMR

(c) < QMN

(d) < RMN

2. m < C = 4x - 6

= 4(25) - 6

= 100 - 6

= 94  so   < C is obtuse.

3. 8x + 2 = 90

8x = 90 - 2

8x = 88

x = 11.

4.

(a).  < DBA and < DBC are  right angles (90 degrees) because BD is perpendicular to AC.

(b) < DBA and < DBC are adjacent and they share the ray BD.

(c) < DBe and < ABE are complementary.

(d) < DBA and < DBC are supplementary

(e)  90 - 40 = 50 degrees

(f) 180 - 40 = 140 degrees.

(g) As the angles are complementary

3x + 2 + 4x + 4 = 90

7x  = 90 - 2 - 4

7x = 84

x = 12.
