Answer:
x=20 degrees
Step-by-step explanation:
complementary means the angles equal 90 degrees
so ∠A+∠B=90 degrees
∠A=3x-2 and ∠B=x+12
so subsitute
(3x-2)+(x+12)=90
then solve for x
4x+10=90
4x=80
x=20 degrees is your answer
Answer:
First question: 1.4
Second question: Option 3
Step-by-step explanation:
First question:
You simplify the left equation first,
-0.4 x -3.5 = 1.4 , -0.4 x 2.9 = -1.16
<u>1.4k - 1.16</u>
For this to equal the right equation, the number missing must be 1.4.
Second question:
You simplify the equation given to you first,
1/4 x 8 = 2 , 1/4 x 12 = 3
<u>2x + 3</u>
The option that is equivalent to the answer is option 3; 2x + 3
Answer:
(5/2)√13 ≈ 9.0139
Step-by-step explanation:
The longer hypotenuse is found using the Pythagorean theorem as ...
The right triangles are AA similar, and vertical sides correspond. Their ratio, smaller/larger is 5/8. That means the hypotenuse of the smaller triangle, A, is 5/8 of the hypotenuse of the larger one.
