Answer:
x=8
Step-by-step explanation:
we know that
If Quadrilateral RSTU is a rectangle
then
The measure of angle STU is a right angle
m∠STU=90°
m∠STU=m∠STR+m∠RTU
so
m∠STR+m∠RTU=90° -----> complementary angles
substitute the given values
(3x-2)+(8x+4)=90°
Solve for x
11x+2=90
11x=90-2
11x=88
x=8
Hello!
To find how many calories in three cups we can use the proportion below.

To find our answer we can say, "How many times does 3/4 go into 3," and then multiply that number by 90 as shown below.
3÷3/4=4
90(4)=
360Just to verify, we will cross multiply and check our answer
90(3)÷3/4
270÷3/4=360
Therefore, our answer is
D) 360 calories.
I hope this helps!
