Answer:

it should equal 68 degrees.

Step-by-step explanation:

if you are looking for the value of m<1, you would first need to find the value of the missing angle on the left triangle. the angles in triangles are equal to 180 degrees, so the equation would be 180 = 50 + 80 + x, and x = 50.

Then move to the middle triangle. The angle you solved for has an angle "connected" to it, its vertical pair, which also equals 50. Then you solve for the last angle, the angle on the right. 180 = 50 + 62 + x, and x = 68.

m<1 is equal to its vertical angle, which is the angle you just solved for. its value should be 68 degrees.

if that wasn't what you were looking for, sorry. hope this helped :)

How do you solve question 27 and 28
Brrunno [24]

Answer:#1 C.30 #2 40


Step-by-step explanation:

3x+15=7x-5

3x+15+5=7x-5+5

3x+20=7x

3x-3x+20=7x-3x

20=4x

20/4=4/4x

5=x so if it is an equilateral all sides are equal so 3(5)+15=30 so the answer should be 30

So the triangle in #2 is an isoceles so two of the angles are equal so the equation is 2(2x-24)+3x+4=180

4x-48+3x+4=180

7x-44=180

7x=224

x=32

2(32)-24

64-24=40

Which number should be added to the expression x^2-8x to change it into a perfect square trinomial?
vovangra [49]

The perfect square (x-a)^2 can be expanded as follows:

(x-a)^2=x^2-2ax+a^2

So, we have to think of the term -8x as -2ax, which implies a=4.

Thus, we have to add a^2, i.e. 16, to complete the perfect square:

(x-4)^2 = x^2-8x+16

What is (are) the solution(s) to the equation 23x−3=−13x−6?
solniwko [45]
From Question ,
23x-3 = 13x-6
Or, 23x-13x = -6+3
Or, 10x = -3
Or, x = -3/10
Therefore x = -3/10 ans

Hope this helps !
