Answer:
18° and 72°
Step-by-step explanation:
let x be the measure of one angle then the other is 3x + 18
The sum of the 2 complementary angles = 90°, hence
x + 3x + 18 = 90
4x + 18 = 90 ( subtract 18 from both sides )
4x = 72 ( divide both sides by 4 )
x = 18
the 2 angles are 18° and (3 × 18 ) + 18 = 72°
204 - 120 = 84
84/120 x 100 = 70%
answer: 70% increase
We are given expression: 
.
Tyna simplified the given expression to 
.
Explanation: In order to simplify , Tyna need to simplify rational expression 
.
On dividing top and bottom by 3, we get 
.
Which Tyna got correct.
Now she need to simplify 
.
<em>On applying quotient rule of exponents, we need to subtract the exponents of x's.</em>
So, it would be 
.
<h3>So, the final answer should be
.</h3><h3>Therefore, Tyan forgot to add exponent to x.</h3><h3>The exponent of x should be 5.</h3>
