<h2>
Answer:</h2>
112.5%
<h2>
Step-by-step explanation:</h2>
100% = 80 - first, you have to write down, what is 100%
1% = 80/100 - than, you need to find out, what is 1% of 80
1% = 0.8
90/0.8 = 112.5% - last step is dividing 90 by 1% of 80
Answer:C
Step-by-step explanation:A function is constant,if as x increases(from left to right) y stays the same
Answer:
a) 10.7 cm
b) 11.6 cm
c) 29.9 cm²
Step-by-step explanation:
a) sin(α)/a = sin(β)/b
sin(∠BCD)/BD = sin(DBC)/DC
sin(41°)/BD = sin(55°)/13.4
BD = 13.4*sin(41°)/sin(55°) = 10.73 cm ≈ 10.7 cm
b) From ΔBCD , ∠BDC = 180-(41+55) = 84°
∠ABD and ∠BDC are alternate interior angles, so they are congruent, and
∠ABD = ∠BDC = 84°
AD²= AB² + BD² - 2*AB*BD*cos (∠ABD) =
= 5.6² + 10.73² - 2*5.6*10.73*cos(84°) = 133.93 cm²
AD =√(133.93) ≈11.6 cm
c) Area(ADB) = (1/2)*AB*BD*sin(∠ABD)=(1/2)*5.6*10.73*sin(84°) ≈ 29.9 cm²
8.8-3.4=5.4
Just subtract 8-3 and 8-4 and you'll get 5.4
Hope it helps!
