Answer:
60
9x=180
x=20
100,20,60
2a=90
a=45,45
y=80
Answer:
1 ) x = 60°
2) x = 20°
P = 3x = 3 × 20° = 60°
Q = x = 20°
R = 5x = 5 × 20° = 100°
3)a = 45°
Y = a = 45°
Z = a = 45°
4) y = 80°
Step-by-step explanation:
1) angle A = 90°
Angle B = x
angle C = 30° (given)
sum of angles of a triangle = 180°
A + B + C = 180°
90° + x + 30° = 180°
120° + x = 180°
x = 180° - 120°
x = 60°
2) P = 3x
Q = x
R = 5x ( given)
sum of angles of triangle = 180°
P+ Q + R = 180°
3x + x + 5x = 180°
9x = 180°
x = 180°
9
x = 20°
NOW P = 3x = 3 × 20° = 60°
Q = x = 20°
R = 5x = 5 × 20° = 100°
3) X = 90°
Y = a
Z = a
sum of angles of triangle = 180°
X + Y + Z = 180°
90° + a + a = 180°
90° + 2a = 180°
2a = 180° - 90°
2a = 90°
a = 90°
2
a = 45°
NOW, Y = a = 45°
Z = a = 45°
4) P = y
Q = 80°
R = 20°
sum of angles of triangle = 180°
P + Q + R = 180°
y + 80° + 20° = 180°
y + 100° = 180°
y = 180° - 100°
y = 80°
