The total is 360°. Your answer would be 120, if you subtract the other angles from 360.

all three sides of triangle x'y'z' must be to the corresponding sides in triangle xyz and the corresponding angles are .
Soloha48 [4]

The required solution is ∠X'≅∠X, ∠Y'≅∠Y and  ∠Z'≅∠Z.

It is required to find the corresponding angles.

<h3>What is angle?</h3>

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Given :

Corresponding angles are

∠X'≅∠X,

∠Y'≅∠Y

∠Z'≅∠Z

Therefore, the required solution is ∠X'≅∠X, ∠Y'≅∠Y and  ∠Z'≅∠Z.

lions [1.4K]

Answer:

first question: 36

second question: 5

Step-by-step explanation:

for the first question, the parentheses just mean you are multiplying. so it would be 2 x 3 x 6 which equals 36.

For the second question, you would add d and g together and e and f, then subtract the sum of e and f from the sum of d and g.

(2 + 12) - (3 + 6)

14 - 9 = 5

given the equation y=-2x^2+1. determine the direction of opening, coordinates of the vertex, Maximum or minimum value and the ax
Andreas93 [3]
The sign of the term in x^2 is negative  so the graph will open downwards.
when x = 0 y = 1
The coordinates of the vertex are (0,1)
the maximum value of the function is 1
and the axis of symmetry ix x = 0 (  the y axis)

NEED HELP ASAP!! WILL GIVE BRAINLIEST! Find the perimeter and area for the triangle. Be sure to write the formula, and use corre
Norma-Jean [14]

Answer:

Area = 77ft²

Perimeter = 44 9/20 feets

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

Base = 19 1/4 feets = 77/4 feets

Height = 8 feets

Area = 1/2 * 77/4 * 8

Area = (77 * 8) / 8

Area = 77 feet²

Perimeter of a triangle :

Sum of the sides

Perimeter = a + b + c

Perimeter = 19 1/4 + 10 + 15 1/5

Perimeter = 44 + (1/4 + 1/5)

Perimeter = 44 9/20
