In this figure, m∠3 = (2x + 15)° and m∠6 = (3x + 10)°. What value of x makes a∥b? Enter your answer in the box.
Dvinal [7]
For First Question:
As, we find the value  of x for parallel condition of line a and b
so, m∠3 = m∠1 and m∠2 = 180°-m∠1 = 180°-(2x+15)° [ As straight line contain total 180°]
Now,
m∠2 = <span>m∠6 [ Because they are corresponding angles]
180</span>-(2x+15)=(3x+10)
180=3x+10+2x+15
x= 31 satisfies the condition of a||b

For second Question:
As, it is issoceles triangle So side AC = side BC So, m∠A=<span>m∠B
</span>4x+5=5x-1
x=6
So,
m∠A=29° and triangle contain total 180° 
<span>m∠C=180-29-29
</span>       =122°

It's really hard for me to understand what they are asking.​
Gekata [30.6K]

Answer:

B is the correct answer

Step-by-step explanation:

Angles 1, 2, and 3 added together should make 180 degrees.

So, if angle 2 is 70 degrees, you subtract 70 from 180 (180-70=110) and you're left with 110 degrees.

Angle 1 and 3 add together should make 110 degrees which makes B the only true statement.

2 for graph 1/2 for equation

Step-by-step explanation:

the rate of change is just another word for slope

using the equation rise/run the slope is 2/1 for the graph

but tin the equation the rate of change is 1/2

(the function is not equal to the graph.)
