What’s the answer for this?

Mathematics
1 answer:
fgiga [73]3 years ago
7 0

Answer:

1.98

Step-by-step explanation:

Use SOH-CAH-TOA:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Here, we're given the hypotenuse is 4.5, and we want to find the side opposite of the 26° angle.  So we should use sine.

sin 26° = x / 4.5

0.44 = x / 4.5

x = 1.98

1.06(12.95+x)=31.27 solve for x
OverLord2011 [107]

Answer:

<h2>x = 16.55</h2>

Step-by-step explanation:

1.06(12.95 + x) = 31.27

<u>Multiply the terms in the bracket</u>

That's

13.727 + 1.06x = 31.27

<u>Subtract 13.727 from both sides</u>

That's

13.727 - 13.727 + 1.06x = 31.27 - 13.727

1.06x = 17.543

<u>Divide both sides by 1.06</u>

That's

\frac{1.06x}{1.06}  =  \frac{17.543}{1.06}  \\ x =  \frac{17.543}{1.06}

We have the final answer as

<h3>x = 16.55</h3>

Hope this helps you

Surface area of the pyramid= 4*(area of the triangle) + area of the square

Area of the triangle = (1/2)*base*height=(1/2)*5*5= 25/2 in²
Area of the square = 5*5 =25 in²

Surface area of the pyramid = 4*(25/2) + 25=2*25 + 25=75 in²
