Answer:
x=1/2
Step-by-step explanation:
Answer:
CAD = 25°
Step-by-step explanation:
The angles are shown to be equal in the figure so BAC = CAD.
Answer:
4
Step-by-step explanation:
I will answer based upon the assumption that you meant:
m - (3/4)m - 1/2 = 2 + (1/4)m
Multiplying all 5 terms by 4 will clear this equation of fractions:
4m - 3m - 2 = 8 + m
Answer:
x= 12
Step-by-step explanation:
∠QPR +∠PQR= ∠HRQ (ext. ∠ of △PQR)
30° +(4x +2)°= (8 +6x)°
32 +4x= 8 +6x <em>(simplify)</em>
<em>Bring x terms on 1 side, constants to the other:</em>
6x -4x= 32 -8
2x= 24 <em>(</em><em>simplify</em><em>)</em>
x= 24 ÷2 <em> (÷2 on both sides)</em>
x= 12
<u>Method</u><u> </u><u>2</u><u>:</u>
∠PRQ= 180° -30° -(4x +2)° (∠ sum of △PQR)
∠PRQ= (148 -4x)°
∠PRQ +∠HRQ= 180° (adj. ∠s on a str. line)
(148 -4x)° +(8 +6x)°= 180°
148 -4x + 8 +6x= 180
156 +2x= 180
2x= 180 -156
2x= 24
x= 24 ÷2
x= 12
