Answer:
vertical angles
∠1 and ∠3 are vertical angles. Their measures are equal, so m∠3 = 90 . ∠1 and ∠2 are supplementary.
Step-by-step explanation:
Remember in every triangle, the sum of the angles adds to 180 degrees. So let us call the smallest angle's measure "A". The largest angle is 3A and the third angle is A+10. So A + 3A + (A + 10) = 180.

x=48 y=30
Step-by-step explanation:
Answer:
<u>$1248</u>
Step-by-step explanation:
I = 960 x 3 x 0.1
= 2880 x 0.1
= $288
<u>Amount </u>
= 960 + 288
= <u>$1248</u>
I = P x r x t
P is the principal amount, $420.00.
r is the interest rate, 3.5% per year
t is the time involved, 5 years
420 × 0.035 × 5 = 73.50
73.50 + 420 = 493.5
