The number 72 should replace the question mark.

Step-by-step explanation:

Step 1:

First, we need to determine how the values inside the triangles were attained in terms of the outer values.

We get that summing the bottom values on the triangle and multiplying it with the value on top equals the value in the triangle.

For triangle 1, (3+5)2 = (8)2 =16,

For triangle 2, (1+7)5 = (8)5 =40,

For triangle 3, (9+2)3 = (11)3 =33.

Step 2:

By using the same method for the fourth triangle we have;

For triangle 4: (3+6)8 = (9)8 =72.

So the question mark equals 72.

Answer:

75°

Step-by-step explanation:

There are 180° in a triangle, so using the ratios and the 180° setup an equation. Solve for x.

5x + 9x + 10x = 180

24x = 180

24x/24 = 180/24

x = 7.5

To find the largest angle measure, use 10x since 10 is bigger than 5 and 9.

10x

10(7.5)

75°

HELP HELP ME PLZ !!!
nikklg [1K]

Answer:

GK=JK

Step-by-step explanation:

SSS congruency  is side-side-side congruency. We are given that GH=JH and KH=KH, which are both sides.

For SSS, we need 3 pairs of congruent sides. We already have 2 pairs.

The options are:

<G=<J

<H=<H

GK=JK

the first two options, <G=<J and <H=<H are talking about congruent angles. We don't need to know about congruent angles for SSS

GK=JK is talking about a pair of congurent sides. Then, we would have 3 pairs of congruent sides, satisfying the criteria needed for SSS. Therefore, we must know that GK=JK.

Hope this helps!

We see that they are made up of identical squares, meaning that each side of each square is the same length. There are 12 square sides that make up the perimeter of A, so we can do 72/12 which is 6. We see there are ten total square lengths on the perimeter of b, so we can do 6 times 10 which is 60 cm. That’s your perimeter.
