OK, so your first step would be to write your equation like this

7x+3=3x+35 because they are corresponding angles therefore they equal each other

Subtract 3 from both sides, this leaves you with 7x=3x+32

Next subtract 3x from both sides so you have 4x=32.

Your last step is to divide 4x and 32 by 4, so you will end up with x=8

Hope this helps!!

Meg is 6 years older than Victor. Meg's age is 2 years less than five times Victor's age. The equations below model the relation

Verdich [7]

Since no possible correct method is posted, I will suggest a couple.

Method 1: guess and check

Works well for simple problems involving integers like this one.

Victor's age must be zero or greater than one, say one.

Guess v=1, find m=v+6=7, check m=5v-2=5-2=3 no good.

we need to make v bigger

Guess v=2, find m=v+6=2+6=8, check m=5v-2=5*2-2=8 ✔

So v=2, m=8.

Method 2:

Solve the system of two equations.

since the left-hand sides is m in both equations, and since m=m, we just have to equate the right-hand sides to solve for v.

5v-2=v+6

Solve for v

5v-v = 6+2

4v=8

v=2,

so again, v=2, m=v+6=2+6=8.

Use the given figure to solve the remaining parts of the triangle AIR.

PIT_PIT [208]

Answer:

1. 15.49 cm

2. 14.39 cm

3. 17.32 cm

4. 11.53 cm

5. 5 cm

Step-by-step explanation:

In the given problem, you can solve the unknown side of the triangle using either Pythagorean Theorem or SOA CAH TOA method. In Trigo, you can use the Pythagorean Theorem if the triangle has 90 degrees, or it is a right triangle.

In the given problem, the angle of the triangles are unknown, therefore to solve the unknown side of triangles, we will you use the SOA CAH TOA.

In this case, since the given side are b and c, we can use CAH (Cos Teta equals Adjacent over Hypotenuse), and TOA ( Tan Teta equals Opposite over Adjacent)

Lets provide the solution for the number, and the rest have the same solutions and process.

b= 17, c= 3, let u is the angle

Cosu= 17/23, to get the angle, use inverse cosine.

The result will be 42.34°, and to get the unknown side, use TOA

Tanu=a/17, a=17Tanu

It will give you 15.49 cm

In the number 2 and 5, it will be the same when you rotate the triangle.
