Given, All sides are equal. So it an equilateral triangle where all the angles are equal.
Sum of the interior angles =180
x+x+x =180
3x=180
x=180/3
x=60

I still don’t get how to do this. Someone help me understand please

solong [7]

Answer:

Step-by-step explanation:

You know that the x-axis is horizontal, so it has slope = 0.

Point-slope equation for line of slope 0 that passes through (-7,9):

y-9 = 0(x+7)

y = 9

Katie has read 34% of a book. If she read 85 pages, does she have more than or fewer than 125 pages left to read? Explain

mestny [16]

Determine the percent of book she hasn't read.
percent = 100% - percent she has read
percent = 100% - 34%
percent = 66%
She hasn't read 66% of the book.

Find the amount of page she hasn't read.
page = $\dfrac{\text{percent hasn't read}}{\text{percent has read}} \times\ \text{page has read}$
page = $\dfrac{66\%}{34\%} \times\ 85$
page = $\dfrac{66}{34} \times\ 85$
page = $\dfrac{5,610}{85}$
page = 165

The number of page she hasn't read is 165. It's more than 125.

Find the measure of angle x in the figure below: (1 point)

Goshia [24]

Answer is C) 51

Angle y is 62 degrees because it forms a straight line with the angles next to it (57 and 61) so angle y must be 62.

There are 180 degrees in a triangle so 180-62-67 = 51
