The question is incomplete. Here is the complete question.
m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.
If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.
A. 1
B. 154
C. 77
D. 26
Answer: B. m∠K = 154
Step-by-step explanation: <u>Isosceles</u> <u>trapezoid</u> is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.
Related to internal angles, angles of the base are equal and opposite angles are supplementary.
In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:
18x + 8 = 11x + 15
7x = 7
x = 1
Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:
m∠J = 18(1) + 8
m∠J = 26
m∠K + m∠J = 180
m∠K + 26 = 180
m∠K = 154
The angle m∠K is 154°

of the birds: 4/15 are birds of prey
If you want to know what fraction of the animals
at the zoo are birds of prey, you can calculate this using the following steps:
4/15 * 3/8 <span>= 12 / (15*8) = </span>1 / (5*2) <span>= </span>1 / 10 = 0.1
<span>Result: In the town zoo, </span>1/10 of animals are birds of prey<span>.</span></span></span>
I’m pretty sure it’s 9/10 - 2/5. I’m sorry If it’s wrong

Step-by-step explanation:
Find the equations to the sequences and solve as equation
5n+20 = 2n+50
5n= 2n +30
3n=30
n=15
