Answer:
measure of exterior angle at C = 160°
Step-by-step explanation:
An exterior angle of a triangle equals the sum of the two remote interior angles
A and B are the remote interior angles. So,
m∠A + m∠B = measure of exterior angle at C
5x - 10 + 12x = 16x
17x - 10 = 16x
x = 10
measure of exterior angle at C = 16x = 16(10) = 160°

Step-by-step explanation:
Answer:
AB = BC = AC = 15
Step-by-step explanation:
Since the triangle is equilateral then the 3 sides are congruent.
Equate any 2 sides and solve for x , that is
AC = AB , so
11x - 7 = 6x + 3 ( subtract 6x from both sides )
5x - 7 = 3 ( add 7 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2
Then
AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus
AB = BC = AC = 15
Answer: 16/24
Step-by-step explanation: Find out a common denominator: 8,16,24 and 3,6,9,12,15,18,21,24. Which is 24.
Take 5/8 multiplied by 3 because its the 3rd multiple of 8. Which is 15/24.
Then, take 2/3 and multiply by 8 because its the 8th multiple of 3. This will give you 16/24.
Make sure to multiply both the top and bottom. :D
