Question

Find the unknown angle
in the figures.
∆PQR,cone P=80° ,cone R=?​

Answer 1

Answer:

CONE R =59

Step-by-step explanation:

in triangle pqr

cone p +cone q+cone r=180 (sum of triangles are 180)

80 + x+x=180

2x=180-80

2x=100

x=50

now in triangle pqr

cone p+cone q+cone r=180 (sum of triangles are 180)

80+50+x=180

130 + x=180

x=180-130

x=50

In Triangel Pqr

Cone P= 80

CONE Q=50

CONE R= 50
