Find the value of x I need help ASAP.

x = 55°

Step-by-step explanation:

We know that a right angle has 90° so,

x + x - 20° =90°

2x - 20° = 90°

2x = 110°

x = 55°

x= 55

Step-by-step explanation:

Since we know they are complementary, we know that their angles would add up to 90 degrees. Let's write an equation setting both angles equal to 90 and solving for x.

(x-20)+x=90

2x-20=90

2x=110

x= 55

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

inverse property is the answer
