Answer:
25
Step-by-step explanation:
Given,
Measurement of <1 = x + 10
Measurement of <2 = 4x + 5
Also, said in the question that both these angles are complementary.
Therefore, by the problem,
<1 + <2 = 90°
=> x + 10 + 4x + 5 = 90
=> x + 4x + 10 + 5 = 90
=> 5x + 15 = 90
=> 5x = 90 - 15 = 75
=> x = 15
Now, we have got the value of x so,
Measurement of <1 is
<1 = x + 10 = 15 + 10 = <u>25 (Ans)</u>
The answer is p>0 because the variable can not be negative so we multiply by negative 1 to get a positive and then the sign switches sides if you need further explanation download PhotoMath
The answer is 4d+8 you have to distribute!
You might have the correct answer !
ANSWER: $66.30
WORK:
to find 15% off, multiply by 0.15.
78 x 0.15 = 11.7
note: this is the percent off, so it's subtracted to find the sale price.
78 - 11.70 = 66.3
