Answer:
43.5
Step-by-step explanation:
Complementary angles add together to equal 180. This is saying that angle Y is the bigger number and that Y=3x+6. You also know that Y+X=180. You can solve bt plugging the equation for Y in.
3x+6+x=180
4x+6=180
4x=174
x=43.5
0.81 = 0.81 / 1
Numerator = 0.81 × 10 × 10 = 81
Denominator = 1 × 10 × 10 = 100
Numerator / Denominator = 81 / 100
Simplifying our fraction
= 81/100
= 81/100
Answer:
749 ft
Step-by-step explanation:
It's a right-angle triangle so you can use trig ratios
750 feet
tan(59) = opposite/adjacent
tan(59l = X/450
X = 450×tan(59)
X = 748.9 ft
X = 749 ft (correct to 3 sf)
