Answer:
Cost: $247
Discount: $133
Step-by-step explanation:
Simply multiply 380 and 35% off together to get your answer:
380(1 - 0.35)
380(0.65)
247
To find the discount amount, simply subtract the 2 numbers to get your answer:
380 - 247 = 133
r° = 158°
s° = 180° - r° = 180° - 158° = 22°
I got 45 for x and 135 for z.
X and 3x are supplementary (they equal 180) x+3x=180 — 45+3(45)=180
Then x and z are also supplementary x+z=180 — 45+z=180
(45-45)+z=180-45
Z=135
Sorry if this is wrong. I did my best, hope it helps
