Sagot :
Answer:
T = 80
U = 20
W = 20
X = 80
Step-by-step explanation:
If two sides of a triangle is equal then it is isosceles and it's base angles are equal as well
Answer:
- Given and explained below.
note 1: total interior angles of a triangle is 180°
note 2: two arrows on opposite sides represents, they have same angle
solve 1:
m∠QPR = 180° - 20° - 80° = 80°
solve 2:
as m∠UST = m∠UTS = 80° because as its an isosceles triangle
m∠SUT = 180° - 80° - 80° = 20°
solve 3:
as m∠XVW = m∠XWV = 20° because as its an isosceles triangle
m∠VXW = 180° - 20° - 20° = 140°
