The base of a triangle is 5?45 cm and the height is 3?88 cm. What is the area of the triangle? Recall: A= 1/2bh
Angelina_Jolie [31]

Answer:

10.57 cm²

Step-by-step explanation:

Recall that the area of a triangle is gotten by (1/2)*base*height

If the height of the triangle is 5.45cm and the base is 3.88cm, then the area can be calculated by multiplying the two numbers and dividing it by 2.

5.45*3.88 = 21.146cm²

This still needs to be cut in half (otherwise we are yielding the area of a rectangle with these dimensions)

21.146 cm²/2 = 10.573 cm²

This can be rounded to the nearest hundredth

= 10.57 cm²

On tuesday And wednesday , cab fare cost $7.75 total. On Monday and Thursday , cab Fare cost $6.30 on each day. On Friday , cab
Rashid [163]
The average daily cost is $7.02.
 
to get the average cost you add up all the prices

 7.75
 7.75
 6.30
 6.30
+7.00
35.10

then you divide that by the amount of numbers you have

35.10 / 5=7.02
 
then there's your answer.

The hypotenuse of a right triangle is 7 feet long. One leg is 4 feet longer than the other. Find the lengths of the legs, Round
Andrews [41]

Answer:

Shorter leg = 2.5 ft.

Longer leg = 6.5 ft.

Step-by-step explanation:

a^2 + b^2 = c^2

Because the hypotenuse = 7 ft, a^2 + b^2 = 49

To represent the two legs, we can use x and x+4.

x^2 + (x+4)^2 = 49

Simplifying this equation using FOIL gives us 2x^2 + 8x - 33 = 0.

Then, using the quadratic formula, we find that x = 2.5.

Thus, the shorter leg is 2.5 ft. and, when 4 is added, the longer leg is 6.5 ft.

What is the missing angle? Please provide an explanation.
irina [24]

Answer:

64 degrees

Step-by-step explanation:

Lets find the measure of the other angle in the other triangle with measures of 84 and 36.

Since there are 180 degrees in a triangle, we just add the other two angles and subtract from 180:

84 + 36 = 120

180 - 120 = 60

So the measure of the other angle in the other triangle is 60. Since there is a right angle we subtract 60 from 90

90 - 60 = 30

So the triangle with the missing angle has two angles with measures of 86 and 30. Now we add the measures and subtract from 180 again.

86 + 30 = 116

180 - 116 = 64

So the missing angle has a measure of 64 degrees
