Answer:

136.73972

Step-by-step explanation:

A=lw+l(w

2)2+h2+w(l

2)2+h2=6·5.2+6·(5.2

2)2+92+5.2·(6

2)2+92≈136.73972

Evaluate.

SVEN [57.7K]

2.3+3.7-2 = 4

27.5 - 4*5.625

= 27.5 - ( 4*5.625)

= 27.5 - 22.5

= 5

I hope that's help !

Step-by-step explanation:

y = 85x+90

3) 85*3+90 (rule)

y= 85*3 = 255 + 90 = 345 (output)

4) 85*4+90 (rule)

y = 85*4= 340 + 90 = 430 (output)

Using the image above, what is the measure of Side AC? Round to the nearest hundredth

Evgesh-ka [11]

To solve this problem, we just have to use trigonometric ratios and apply which of the ratios is needed here and proceed to solve. The value of side AC is 2.85 units

<h3>Trigonometric Ratio</h3>

In the given diagram, we have the value of angle and hypothenuse and we are required to find the adjacent side of the triangle.

Data;

Angle = 32.9 degrees
Hypothenuse = 3.4

Let's use cosine rule for this.

$cos\theta = \frac{adjacent}{hypothenuse}$

Proceed to substitute the values into the equation and solve.

$cos 32.9 = \frac{AC}{3.4} \\AC=3.4cos32.9\\AC = 2.85$

From the calculations above, the value of side AC is 2.85 units
