7x - 1 + 6x - 1 = 180
13x - 2 = 180
13x = 182
x = 14
Larger triangle’s base length
a^2 + b^2 = c^2
a^2 + 3^2 = 8^2
a^2 = 8^2 - (3^2)
sqrt(a^2) = sqrt(55)
a = sqrt(55)
__________________
Smaller triangle’s base length:
The same formula applies.
a^2 + 3^2 = 5^2
a^2 = 5^2 - (3^2)
sqrt(a^2) = sqrt(16)
a = 4
____________
The finale!
Add the two side lengths of a, which is sqrt(55) + 4 (exact answer)
or... 11.416 (unrounded to thousandths place)
Good luck to you!
Answer:
7y
Step-by-step explanation:
Answer:
58
Step-by-step explanation:
Order of operations.
Additions and subtractions, in the order they appear, from left to right.
30 + 30 - 2 =
= 60 - 2
= 58
Answer:
150 degrees
Step-by-step explanation:
Use the equation below to find the sum of all the interior angles in this polygon:
(number of sides - 2)*180
number of sides = 6
(6-2)*(180) = 4*(180) = 720
Now that you know the total sum, subtract all other angles to find x:
720 - 90 - 162 - 101 - 96 - 121 = 150
