Answer:

C. 45 degree angle

Step-by-step explanation:

let AB be the height of the wall and CD be the height of boy

with BC as distance between them.

we have AE = AB-BE = 3.64-1.54 = 2.1m

and ED = BC = 2.1m

in triangle AED, we have

tanФ = P/B = 2.1/2.1

tanФ = 1

∴ Ф = 45°

Hence the sun is elevated at an angle of 45 °.

1. To solve this exercise, you must apply the formula for calculate the area of a trapezoid, which is shown below:
<span> 
 A=(b1+b2/2)h
</span><span> 
 A is the area of the trapezoid.
</span><span> b1 is the larger base of the trapezoid (b1=16-4=12 ft).
</span><span> b2 is the smaller base of the trapezoid (b2=10-4=6 ft).
</span><span> h is the height of the trapezoid (h=12-4=8 ft)
</span><span> 
 2. When you substitute these values into the formula A=(b1+b2/2)h, you obtain:
</span><span> 
 A=(b1+b2/2)h
</span><span> A=(12 ft+6 ft/2)(8 ft)
</span><span> A=9 ftx8ft
</span><span> A=72 ft² 
</span><span> 
 3. </span><span>The length of fencing is:</span>  a²=b²+c² a=√b²+c² a=√(8 ft)²+(6 ft)² a=10 ft  Perimeter (Length of fencing)=12 ft+8 ft+6 ft+10 ft=36 ft

Marissa notices that the top of the net is 20 inches higher than the tallest player on the team. The net is less than 90 inches
Vika [28.1K]
No, the inequality uses less than or equal to, but it should be less than. The relationship could be written as h<span> + 20 < 90. This says that the tallest player’s height plus 20 inches is less than 90 inches.</span>

A TV that usually sells for $178.09 is on sale for 30% off. If sales tax on the TV is 5%, what is the price of the TV, including
marusya05 [52]
178.09 \times \frac{70}{100}\times \frac{105}{100} = \frac{178.09 \times 70 \times 105}{100\times 100} = \frac{1308961.5}{10000} = 130.89615 \approx \boxed{130.90}

Your answer is $130.90

Note: We multiply by 70/100 because of the 30% discount. 100 - 30 = 70. So we have to multiply by 70%.

Also, we multiply by 105/100 because there is 5% tax. The tax means that we have to pay more which means 100 + 5 = 105.

Hope this helped :D
