GEOMETRY- What is the area of the figure, show your work please!
Kamila [148]
Since this is a 45-45-90 right triangle, the hypotenuse = sqrt2 * leg
24 is the hypotenuse so we need to find the leg.
24 = sqrt2 * leg
Divide both sides by sqrt2
leg = 16.97
A = (1/2)b*h
A = (1/2)*16.97*16.97
A = 144ft^2

Solve for x. Round to the nearest tenth if necessary.
timofeeve [1]

Answer: 41.1

Step-by-step explanation:

To find the value of x, we need to use SOH-CAH-TOA. SOH-CAH-TOA is since, cosine, and tangent. The O, A, H stands for opposite, adjacent, and hypotenuse respectively.

Looking at the figure, we see 47°. The labelled angles are adjacent and the hypotenuse. Therefore, we use CAH or cosine.

cos(47)=\frac{28}{x}             [multiply both sides by x]

xcos(47)=28           [divide both sides by cos(47)]

x=\frac{28}{cos(47)}

When we plug that into a calculator, we get x=41.1.

Solve the equation, 4 - (x + 1) = 6.​
elena-14-01-66 [18.8K]

Answer:

x = - 3

Step-by-step explanation:

4 - (x + 1) = 6

- (x + 1) = 6 - 4

-x - 1 = 6 - 4

-x - 1 = 2

- x = 2 + 1

- x = 3

x = - 3

If you need the process explained more in depth just let us know
