Answer:
Measure of exterior angle ABD = 136°
Step-by-step explanation:
Given:
measure of ∠A = (2x + 2)°
measure of ∠C = (x + 4)°
measure of ∠B = x°
Find:
Measure of exterior angle ABD
Computation:
Using angles sum property
∠A + ∠B + ∠C = 180°
So,
(2x + 2) + (x + 4) + x = 180
4x + 6 = 180
4x = 176
x = 44
So,
measure of ∠B = x°
measure of ∠B = 44°
Measure of exterior angle ABD = 180 - measure of ∠B
Measure of exterior angle ABD = 180 - 44
Measure of exterior angle ABD = 136°
Answer:
<em>The difference is 30 hours</em>
Step-by-step explanation:
<u>Proportions</u>
Safie can write a minimum of 5 questions per hour and a maximum of 11 questions per hour.
To write 275 she takes a maximum of 275/5=55 hours and a minimum of 275/11=25 hours.
The difference is 55 hours - 25 hours = 30 hours
Use the Pythagorean theorem

to find the missing side length of a right triangle
In this case, after you plug in the given numbers your equation is

Then, Just solve that equation for y.



y = 16
So the answer is B, 16 cm.
I hope this helps, please feel free to ask questions if you're still confused :)
Answer:
x = 12
Step-by-step explanation:
20° + (6x - 2) = 90°
18° + 6x = 90°
6x = 90° - 18°
6x = 72°
x = 72°/6
x = 12
