Does anyone know how to do this it’s geometry angles . And you have to make an equation if you know this please help.

Step-by-step explanation:

Problem 1)

The given angle is a right angle with measure 90° so

2x + x = 90°

3x = 90°

x = 30°

Problem 2)

The given angle is a straight angle with measure of 180°

2x + 3 + x - 6 = 180° add like terms

3x - 3 = 180°

3x = 183°

x = 61°

Problem 3)

The given angles are corresponding angles with same angle measurement

x + 16 = 4x - 5

21 = 3x

7 = x

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
