Answer:
B) ∠z = 40°
Step-by-step explanation:
<u>All three angles of a triangle add up to 180°</u>. In this image, you can see that the angle ∠ACD is 130°. Because ∠ACB and ∠ACD are supplementary angles it means that their angles equal 180° when added together.
If ∠ADC = 130° then:
180° - 130° = 50°
Since we now know that ∠ACB is 50°, we can subtract our two angles from 180° to get the measurement for angle z.
180° - 50° - 90° =
180° - 140° = 40°

The last statement represents an impulse purchase:
Tara goes to the pet store for fish food. She visits the pet adoption center and quickly decides to adopt a dog without considering all of the costs in caring for the dog.
Answer:
the answer is 60.0
Step-by-step explanation:
28.8+12+18=58.8
rounded to the nearest 10th would be 60.0
We simplify this expression by using the FOIL method, and get 2x²+10x-3x-15 = 2x²+7x-15.
