Answer:
Triangle = 180 Degrees, so 77.
Step-by-step explanation:
42+35+x=180
x = 77
Number one is really easy just set it up in proportions. 420 over x and 7 hours over 24 cause you know there 24 hours in a day and then cross division and simplify. I think.
1,876,200 - if it's higher than 5 go up - that means 1,880,000
1,876,200 - means 1,900,000
1,876,200 means 2,000,000
Answer:
x ≈ 14.5
Step-by-step explanation:
A = x²√(25+10√5)/4
A = 1.72a²
x² = A/1.72
= 363.27/1.72
≈ 211
x = √211
≈ 14.5
