The triangles KLH and FLH are congruent by the hypotenuse leg theorem (HL theorem for short) because KL = LF is one pair of congruent legs and LM = LM is the pair of congruent hypotenuses. This theorem only works for right triangles.

By CPCTC (corresponding parts of congruent triangles are congruent), this means we can say that the bottom two angles KHL and FHL are congruent

So,

angle KHL = angle FHL

6y = 4y+18 ... substitution

6y-4y = 4y+18-4y .... subtract 4y from both sides

2y = 18

2y/2 = 18/2 ... divide both sides by 2

y = 9

Answer: 9

Given: NQ = NT , QS Bisect NT(∴ NS=ST ) , TV Bisects QN (∴ NV=VQ )

To Prove: QS=TV

Proof: In ΔNQT

NQ=NT

\frac{1}{2}NQ=\frac{1}{2}NT

∴ VQ=ST

In a isosceles triangle, If two sides are equal then their opposites angles are equal.

∴ ∠NQT=∠NTQ       ( ∵ NQ=NT)

In ΔQST and TVQ

ST=VQ                    (sides of isosceles triangle)

∠NQT=∠NTQ          (Prove above)

QT=TQ                    (Common)

So, ΔQST ≅ TVQ  by SAS congruence property

∴ QS=TV  (CPCT)

CPCT: Congruent part of congruence triangles.

Hence Proved

I WILL GIVE BRAINLIST AND 50 POINTS
Alisiya [41]

Step-by-step explanation:

A proportional relationship graph would show that the points can be arranged in a line that passes through the origin.

All of the points in Graphs B, C and D cannot be connected in 1 straight line, hence they are not proportional relationships.

Only Graph A shows a proportional relationship.

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag. What is the theoretical probability of randomly drawing
grigory [225]

Answer:

25%

12/25

Step-by-step explanation:

5+8+12 = 25 possibilities+

We know that

Red marbles = 5

Blue Marbles = 8

Green marbles = 12

The probability of finding a green marble will be 12/25, with a total of 25.
