Answer:
-4
Step-by-step explanation:
Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.
So to solve for x, set 28 and 10x+68 equal to each other.
28=10x+68
First, subtract 68 from both sides
-40=10x
Then, divide both sides by 10
-4=x
If you want to check your answer plug -4 back into the original equation.
28=10(-4)+68
28=-40+68
28=28, which is true, therefore -4 is correct.
Answer:
x = 9
Step-by-step explanation:
3(3x + 5) = 96
Divide both sides by 3.
3x + 5= 
Divide 96 by 3 to get 32.
3x + 5= 32
Subtract 5 from both sides.
3x = 32 − 5
Subtract 5 from 32 to get 27.
3x = 27
Divide both sides by 3.
Divide 27 by 3 to get 9.
Hope it helps and have a great day! =)
Since the triangle is isosceles we know that angle a is equal to angle c.
8y-7=73
8y=80
y=10
We also know that the sum of the interior angles in any triangle is 180 degrees.
73+73+6x+4=180
150+6x=180
6x=30
x=5
Y= -0.7 + -2
P.S (the slope is actually -0.666667 but I rounded it to -0.7)
390-35=355

355/10=35.5
