Answer:

2x= 40°

5x= 100°

Step-by-step explanation:

2x on opposite angle because it is an isosceles triangle

2x+ 2x+ 5x = 180° (angles of a triangle)

9x= 180

x= 180/9

x= 20°

Sub

2(20)= 40°

5(20)= 100°

I’ve been stumped on this question for a while (picture included)
julsineya [31]

Answer:

Since the question is indicating to use a graphing calculator, we can assume that we would be required to graph both of the equations.

Red = \sqrt{x+2}

Blue = 3x^2-4x-1

By graphing those equations, we can determine the solution(s)

The points where the graphs intersect would be your coordinates to derive your solution

Red = (1.864, 1.966)

Blue = (-0.427, 1.254)

The solutions would be the x-value of the ordered pair, in this case,

x = 1.864 AND x = -0.427

last weeekend trisha and becca both went on a bike ride trisha biked 8 miles in two hours and becca biked 10 kilometers in 7800
S_A_V [24]
So first I’m going to change the 10 kilometre in miles which is 6.214 miles
Then I’m going to convert 7800 seconds in hours which is 2.16 hours so now the data shows that Trisha biked 8 miles in 2 hours and becca biked 6.214 miles in 2.16 hours
So Trisha was faster than becca

A triangle has side lengths of (q+r)(q+r) centimeters, (5q-10s)(5q−10s) centimeters, and (5s-7r)(5s−7r) centimeters. Which expre
Stolb23 [73]

The expression represents the perimeter, in centimeters, of the triangle is 6q - 6r - 5s

<h3>What is the perimeter?</h3>

The formula for perimeter of a triangle is expressed as;

Perimeter = a + b + c

Where a , b and c are the lengths of its side

  • (q+r)
  • (5q-10s)
  • (5s-7r)

Now, let's substitute the values

Perimeter = (q + r) + (5q - 10s) + (5s - 7r)

expand the bracket

Perimeter = q + r + 5q - 10s + 5s - 7r

collect like terms

Perimeter = q + 5q + r - 7r -10s + 5s

Add like terms

Perimeter = 6q - 6r - 5s

Thus, the expression represents the perimeter, in centimeters, of the triangle is 6q - 6r - 5s
