Answer:
B.) 113°
Step-by-step explanation:
In the isosceles trapezoid, angles T and S are congruent. Find the value of x:

Subtract 4x from both sides:

Add 38 to both sides:

Divide both sides by 3:

x is equal to 15. Now substitute the value of x into the one of the expressions:

or

The angles T and S are 67°.
The angles of a trapezoid will always add up to a total of 360°, so add the angles T and S:

Subtract their total from 360:

The total of the angles Q and R is 226°. Since this is an isosceles trapezoid, those two angles are also congruent. Divide the value by 2:

Angle R is 113°.
Done.

Answer:
It's 21.
Step-by-step explanation:
The factors of 9 are 3 and 3. (You need to multiply 3x3 to get 9.) The factors of 10 are 5 and 2. But, if you multiply 3 by 5, which gives you 15, and multiply the other 3 by 2, which gives you 6, and then add 6 to 15, you get 21.
