Answer:
Step-by-step explanation:
The triangle KLM is shown in the attached photo. The sum of the angles in a triangle is 180 degrees. It means that
angle K + angle L + angle M = 180 degrees. Since
m angle K=(10x+10). m angle L=(9x-3). m angle M=(7x-9), then
10x + 10 + 9x - 3 + 7x - 9 = 180
10x + 9x + 7x = 180 + 9 + 3 - 10
26x = 182
x = 182/26
x = 7
m angle K=(10x+10) = 10×7 + 10 = 80 degrees
m angle L=(9x-3) = 9×7 - 3 = 60 degrees
m angle M=(7x-9) = 7×7 - 9 = 40 degrees.
The triangle is an acute triangle because each angle is lesser than 90 degrees
The triangle is scalene triangle because non of the sides are equal.

Answer:
Your answer is 58
Step-by-step explanation:
This is true because complementary means both angles add to 90 degrees. So if you know one is 32 then you subtract 90-32 which will give you 58 (angle B).

Answer:
25%
Step-by-step explanation:
Apparently, we're to assume that anything not spent is saved.
Let Hideo's income be 1. Then Akira's income is 5/8. Akira's expenses are 60% = 3/5 of that value, so ...
Akira's expenses = (3/5)(5/8) = 3/8 . . . . . of Hideo's income
Hideo's expenses are twice this amount, so ...
Hideo's expenses = (2)(3/8) = 3/4 . . . . . of Hideo's income
That means Hideo saves 1 -3/4 = 1/4 = 25/100 = 25% of his income.
Hideo saves 25% of his income.
Answer:
I think its 6.25 (6 and 1/4) but I'm not a teacher or anything so it may be incorrect.
