Answer:

∠A = 32°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tanA = $\frac{opposite}{adjacent}$ = $\frac{5}{8}$ = 0.625, thus

A = $tan^{-1}$ (0.625) = 32°

Jennifer needs to make an average of at least $350 per week. If she makes $385, $326, and $298 for the first 3 weeks of the mont

ella [17]

385 + 326 + 298 = 1,009 / 3 = 336.33

385 + 326 + 298 + x = 350

350 x 4 = 1,400
1,400 - 1,009 = 391

385 + 326 + 298 + 391 = 1,400 / 4 = 350

The answer is $391

The measure of angle x is 18 more than 3 times the measure of its complement.

Alex

Complementary angles = two angles that add to 90° complement each other.

So, angle x = 3y+18
y= complementary angle
(3y + 18) + y = 90
4y+18 = 90
4y=72
y=18°

x= 3y+18
x= 3(18) +18
angle x = 72°
