Answer:
7
Step-by-step explanation:
Complementary angles = two angles that add to 90° complement each other.
So, angle x = 3y+18
y= complementary angle
(3y + 18) + y = 90
4y+18 = 90
4y=72
y=18°
x= 3y+18
x= 3(18) +18
angle x = 72°
Answer:
The correct option is 70
Step-by-step explanation:
It is a right triangle so we will use Pythagorean theorem to find AB:
We have One side = 24 and hypotenuse = 24+50 which is 74
Now apply Pythagorean theorem:
AB = √(74)²-(24)²
AB = √5476-576
AB= √4900
Take the square root of 4900.
AB= 70
Thus the correct option is 70....
20 rows x 18 seats per row= 360 after that is 5 dollars for the cost of the tickets so multiply 360 by 5 and you will get the answer of 1800.
