Answer:

first answer is 7 square root 2, second is 39, third is 5.36487494991.

Step-by-step explanation:

1st answer: its a right triangle with both sides as 45 degrees no shorter legs or longer legs. so both opp and adj legs are equal to 7. 7 times 7 plus 7 times 7 is 98 so square it into radical form and get 7 square root 2. second is 39 because of the 3,4,5. 15 36 and 39 are ratios of the rule. Third is 5.45454545... because make a triangle with a right triangle properties. name the hyp variable A. Find each angle which is 90, 56 ( the top of the triangle where plane is ) and 34 ( at the boat place ). You use Sine with 34 which is (0.55919290347...). This is equal to 3 km over A. Change the form and turn it into A=3 divided by 0.55...) which is 5.36487494991.

D.) is 13/5 it got cut off<br> HELP NEEDED<br> [10 points up!]

vodomira [7]

It would be A. You can find this out by using SOH CAH TOA,

SOH means sin= opposite/hypotenuse

CAH mean cos= adjacent/hypotenuse

TOA means tangent= opposite/adjacent

You would use CAH since you are trying to find cos∠C

You would have cos∠C=10/26.

26 is the hypotenuse since it is opposite the right angle and is the biggest side.

10 is the adjacent since it is right next to C

You would simplify this down to 5/13 by dividing by 2.

This gives you A.

Find the area of the shaded region.

taurus [48]

Answer:

$426.96 \: {km}^{2}$

Step-by-step explanation:

Area of the shaded region = Area of triangle with base 40 km and height 27 km - Area of circle with radius (12/2) 6 km.

$= \frac{1}{2} \times 40 \times 27 - 3.14 \times {(6)}^{2} \\ \\ = 20 \times 27 - 3.14 \times 36 \\ \\ = 540 - 113.04 \\ \\ = 426.96 \: {km}^{2}$

For the straight line defined by the points (2,55) and (4, 87), determine the slope (m) and y-intercept?

mamaluj [8]

Answer:

Slope(m) = 16

Y intercept (c) = 23

Step-by-step explanation:

Given:

Points : (x1, y1) = (2, 55)

(x2, y2) = (4, 87)

Using two point form to calculate slope:

$m = \frac{y2-y1}{x2-x1}$

$m = \frac{87-55}{4-2}$

m = 16

To find y intercept:

Take any one point ans slope :

Using slope point formula:

y = mx + c

87 = 16(4) + c

Solving for c:

c = 23
