Answer:

1, 4, 5

Step-by-step explanation:

Consider right triangle JKL with right angle JKL and height KM. This height divides triangle into two right triangles KML and KMJ.

Note that

m\angle MKL=90^{\circ}-m\angle MLK=m\angle KJM\\ \\m\angle JKM=90^{\circ}-m\angle KJM=m\angle MLK

So, by AA theorem, we have three similar triangles

\triangle JKL\sim \triangle JMK\sim \triangle KML

So, options 1, 4 and 5 are true

A book club has 36 members. There are 24 boys and 12 girls in the club. What is the ratio of the number of boys in the club to t
Ivanshal [37]

Step-by-step explanation:

Ratios can be written as:

a to b

a:b

a/b

We want to find boys to girls, and there are 24 boys and 12 girls. So, we can write it as

24 to 12

24:12

24:2

All of these can be reduced, since both the numerator and denominator can be divided by 12.

Numerator: 24/12=2

Denominator: 12/12=1

2 to 1

2:1

2/1

Pls help?!?!?!?!?!??!!
harkovskaia [24]

Answer:

m<A = 120°

m<C = 45°

Step-by-step explanation:

We can use the triangle sum theorem to find the measures of the angles.

m<A + m<B + m<C = 180°

Then substitute in their given values.

12x + 12 + 15 + 3x + 18 = 180°

Now simplify the equation and you get

15x + 45 = 180°

Continue to solve

15x = 135

x = 9°

Now substitute this value of 9 for the angle expressions of <A and <C

(12 x 9) +12 = m<A

m<A = 120°

(3 x 9)+ 18 = m<C

m<C = 45°

Hope this helps. To check your answer you can add up all the answers to see if it equals 180°.
