In parallelogram PQRS, QP is extended to point T and ST is drawn. If ST = SP and m∠R = 130°, what is m∠PST?
Answer: 80°
Step-by-step explanation:
ST = SP and m∠R = 130°
If m∠R = 130°, then,
QPS = 130° ( Opposite angles of a parallelogram are equal)
QPS + SPT = 180° (angle on a staght line)
130° + SPT = 180°
SPT = 180° - 130° = 50°
PTS = SPT = 50° (Base Angle of an isosceles triangle)
m∠PST = 180° - (50° + 50°) (sum of Angle in a triangle)
m∠PST = 80°
Answer:
55m^2
Step-by-step explanation:
you didn't show the actual figure but I'm going to assume the triangles are made up of a vertical of the rectangle bc of the answer choices meaning the shaded triangle is likely half the area of the rectangle
3/12=1/4 simplified and in decimal form it is .25 so it is RATIONAL because it ends. A rational number is any number that can be put into a form of a/B and B doesn't equal zero
Using the substitution method, we can plug equation 1 into equation 2 (in place of x) as a result we see:
<span>x + 4 = 3x + 6</span><span /><span>
</span>
Answer:
B) M-5
Step-by-step explanation:
the commutative property does not apply to subtraction or division, only addition and multiplication
