In triangle ABC, if AC is congruent to CB, angle A = 3x + 18, angle B = 7x - 58, & angle C = 2x - 8, find x & the measur

sukhopar [10]

Answer:

Angle A = 75°

Angle B = 75°

Angle C = 30°

Explanation:

If AC is congruent to CB, from figure given we have angle A = angle B.

Angle A = 3x + 18

Angle B = 7x - 58

Angle C = 2x - 8

We have,

3x + 18 = 7x - 58

4x = 76

x = 19

So,

Angle A = 3*19 + 18 = 75°

Angle B = 7*19 - 58 = 75°

Angle C = 2*19 - 8 = 30°

Can someone explain to me the letter or sign or variable after "Y"

sattari [20]

Answer:

It is a symbol used to denote an angle (or something else)

Step-by-step explanation:

Alpha(α) is a greek letter, it's one of the letters used to denote angles. Other such letters you'll often see in math are Beta (β), Gamma (γ), Delta (δ), these are used to denote angles. Also, pi (π), which is a mathematical constant. The letters phi (φ) and theta (θ) are also used for angles very often, especially in formulas. You'll see some of these in physics too.

It can be used as variable too, not necessarily for angles, but it's mostly used for them.

I need help can I don’t know how to do this problem

Elden [556K]

Answer:

a ^ (1/12)

Step-by-step explanation:

a ^ (1/3)

---------------

a ^ (1/4)

We know that b^ c / b^ d = b ^ (c-d)

a^ (1/3 - 1/4)

getting a common denominator

1/3 *4/4 - 1/4*3/3 = 4/12 - 3/12

a^ (4/12 - 3/12)

a ^ (1/12)

The table shows values for functions f(x) and g(x) What is the solution to f(x)=g(x) ?

Fynjy0 [20]

Answer:

x = 1

Step-by-step explanation:

You are looking for the value of x that makes f(x) = g(x). In the table, the values for f(x) and g(x) will be the same for some value of x. That value of x is the solution.
