<span>3x + 2x = 90 {the two angles add up to 90°}
5x = 90 {combined like terms}
x = 18 {divided both sides by 5}
angle 1 = 3x
= 3(18) {substituted 18, in for x, into 3x}
</span><span>= 54° </span><span>angles add up to 90°
angle 1 = 3x
angle 2 = 2x

Answer:1/2
Step-by-step explanation:
Given parameters:
First number = 7.92 x 10⁷
Second number = 7.2 x 10³
Quotient is the number obtained division;
Now;

=
x 10⁷⁻³
= 1.1 x 10⁴
The quotient of the two numbers expressed in scientific notation is 1.1 x 10⁴
ANSWER:
12x
“A number” just means a variable normally
