Complementary means they add to 90°
f=90-g
f=4g
4g =90-g
5g=90
g=18
f=4g=4(18)=72
Answer: f=72°, g=18°
Yes the answer is not 4/7 its 7/4
For the first question: The equation would be set up as 30=1/2(12x) Then solve for x. (Or just plug that formula into Desmos)
Answer: x=5
Answer:
Step-by-step explanation:
–5 × 0.75 × 20 could be rewritten (applying the associative property) as –5 × (0.75 × 20). I chose this configuration because 0.75 * 20 is 15. Next, evaluate -5(15). This is -75. This matches Answer D.
Step-by-step explanation:
Hypotenuse² = (Leg 1)² + (Leg 2)²
= (8)² + (15)² = 289
Hence the hypotenuse is 17cm.
