The answer you are looking for is the part d
Answer:
Part A) x = 5
Part B) B = 113 degrees, C = 95 degrees. E = 95 degrees
Step-by-step explanation:
<u>Part A:</u>
We know that the sum of all angles in a pentagon are 540 degrees.
We already have two angles: 113 and 124 which add up to 237.
Make an equation out of all the information.
237 + 98 + 3x + 19x - x = 540
3x + 19x - x = 105
21x = 105
x = 5
<u>Part B:</u>
Substitute 5 for each x
measure B: 98 + 3x = 98 + 3*5 = 98 + 15 = 113
measure C: 100 - x = 100 - 5 = 95
measure E: 19x = 19* 5 = 95

Answer:
x= 7, -13
Step-by-step explanation:
No because equivalent is like 5/10 so it's not right
To calculate the perimeter of an isosceles triangle, the expression 2s + b is used, where s represents the length of the two congruent sides and b represents the length of the base.
I may not know the answer but I know how to get it just follow the rule. Sorry if I didn’t help.
