Answer:
Step-by-step explanation:
V = 30 and Ab = 6 into our height formula, and simplify as follows: h = V / Ab = 30 / 6 = 5.

x = 7
Explanation
5/40 = 3/2x+10 ( Proportionality ) Theorem)
Cross Multiply
10x + 50 = 120
10x = 70
x = 70/10
x = 7
Answer: the equation is 2n-10
Answer:
a = 98
b = 82
c = 58
d = 122
Step-by-step explanation:
Ok so I tried to find b first since that was the easiest.
The other side from b is going to be 98 because of the vertical angles theorem, and adding 98 with b will be 180 because of supplementary angles.
180-98=b
82=b
I looked for letter a next. I used the alternate interior angles with letter a and the other side of b. Alternate interior angles always equal each other so therefore the opposite from letter a is 82. 180-82=98
C is 58 from an interior angles theorem I learned a year ago and forgot (sorry. hmm i think its called corresponding angles theorem)
And letter D is found by taking the vertical angle from C and giving it the value of 58 since C is also 58. Now we know that the other side from d is 58 and adding 58 with d will get us 180 since they are both supplementary angles.
d+58=180
d=122
Sorry for my sketchy explanation I learned this a year ago and I don't remember the names of the explanations well
