Answer:
Isosceles trapezoid
Step-by-step explanation:
-An isosceles trapezoid is also sometimes called a convex quadrilateral.
-It properties include:
- A line of symmetry can often bisects a pair of opposite sides.
- It has to obtuse alternating with each other after which a pair of acute angles alternate with each other i.e 80°, 80°,100°,100°
- It has a trapezoidal shape which by definition has a two pair of parallel sides.
- The angles on it's base or ceiling are equal hence the name Isosceles Trapezoid.
245-132=x
since riley has 132 out of 245, you would subtract her number from the original number and get sierra's number of minutes which is x
Answer:
A
Step-by-step explanation:
Total angle of each triangle=180°
From the question, the shapes of both triangles are just the same
x=40°
y=60°
a+60°+x=180°
a+60°+40°=180°
a=80°
b+40°+y=180°
b+40°+60°=180°
b=80°
a=b
