Answer:
168). C
169). C
170). C
Step-by-step explanation:
For the first angle, it is a right angle, so it measures 90 degrees.
x and 50 are complementary angles, meaning they add up to 90 degrees.
So, subtract 50 from 90 to get 40, which is equal to x.
45 and x are supplementary angles, meaning they add up to 180 degrees.
Subtract 45 from 180 to get 35 degrees, which is the measure of angle x.
All angles in a triangle add up to 180 degrees.
So, 70 + 56 = 126, 180 - 126 = 54.
Since the unknown angle is x - 5, 54 + 5 = 59, which the the measure of angle x - 5.
Answer:
31.5 units^2
Step-by-step explanation:
This is a right triangle
The x dimension is from B to C
-4 to 3 is 7 units
The y dimension is from A to B
5 to -4 = 9 units
The area of a triangle is
A = 1/2 bh
A = 1/2 (7)(9)
= 31.5
Answer:
3x - 6 = -10. - 3x = -4!
2x - 6 = 5x-10
Step-by-step explanation:
2x-(3-4y), when x = 5 and y=-3. 215)-(3-4(-3)). 10-(3+12). 10-15. 2. ... by 5 to clear the fractions. 2x - 6 = 5x-10. - 3x - 6 = -10. - 3x = -4.
Earnings: $2900
Expenditure on food: $290
Percentage expenditure on food = Expenditure on food / Earnings times 100
= $290/$2900 * 100 = 10%
9 * 8 * 10 * 2981
72 * 10 * 2981
720 * 2981
2, 146, 320
Hope this helps!
