find the value of x in the triangle shown below.

Answers

Answer 1

Answer:

61 degrees

Step-by-step explanation:

You can see that the triangle is isosceles which means the base angles are equal because of BAT.

Now you can just use the sum of angles in a triangle to find the measure of x. (180)

180-58=122

122/2=61

If one leg of a right triangle is 4/7 and the hypotenuse is 10/6, then the other leg is

Answers

A right triangle has two legs and a hypotenuse
a = shorter leg
b = longer leg
c = hypotenuse
We know b-a=4, or b = a+4

The Pythagorean theorem states:
a2 + b2 = c2

a2 + (a+4)2 = c2
a2 + (a+4)2 = 80
a2 + a2 + 8a + 16 = 80

Combine terms
2a2 + 8a - 64 = 0

Divide by 2
a2 + 4a - 32 = 0

Factor
(a+8)(a-4) = 0
a = 4, -8

We throw out the -8 solution because we can't have a negative measure.

So a = 4
b = 8
c = √80 = 4√5

The legs are 4 and 8.

410 people were surveyed about their favorite color. The circle graph created from the results shows that the slice for red measures 130 degrees. How many people said their favorite color was red?

Answers

148 people

Since we know that the total number of people is 410, we know that the whole circle is equal to 410 people. We know that a full circle is 360 degrees, so our group would be 130 degrees of those 360, or 130/360. Since one complete circle is 410 people, we multiply this by 130/360 to find the number of people that said red is their favorite color is 148.

Answer:

44m²

Step-by-step explanation:

GIVEN :-

Lengths of all the sides of the figure.

TO FIND :-

Area of the figure

SOLUTION :-

Divide the whole figure into 2 rectangles.

Dimension of 1st rectangle = 6m × 2mDimension of 2nd rectangle = 8m × 4m

Area of 1st rectangle = 6 × 2 = 12m²

Area of 2nd rectangle = 8 × 4 = 32m²

∴ Area of the whole figure = 32 + 12 = 44m²

A man earns 15000 in a month. if he spends 20% on food and 10% in his children's education.
a) what is his total expenditure?
b) how much does he save in a month?

Answers

Step-by-step explanation:

Total money=15000

food=20%

edu.=10%

food AMT=20% of 15000

=20/100*15000

= 3000

education AMT= 10/100*15000

=1500

savings = 15000-1500-3000

=Rs10500

total expenditure=1500+3000

=4500

Laura is bowling 5 games. Her first 4 scores were 103, 143, 101, and 110.
To end up with an average score of at least 126.8, what is the lowest score Laura will need in the fifth
game?

Answers

Answer:

The least 5th score is 177

Step-by-step explanation:

Given

[tex]First\ 4: 103, 143, 101, 110.[/tex]

[tex]Average = 126.8[/tex]

Required

The least 5th score

Represent the 5th score with x.

The average is calculated as:

[tex]Average = \frac{\sum x}{n}[/tex]

So, we have:

[tex]126.8 = \frac{103 + 143 + 101 + 110 + x}{5}[/tex]

[tex]126.8 = \frac{457 + x}{5}[/tex]

Multiply both sides by 5

[tex]634= 457 + x[/tex]

Solve for x

[tex]x = 634- 457[/tex]

[tex]x = 177[/tex]

A developer is building a scale model of the city. From the roof of an apartment complex, the developer points two lasers at the taller office building across the street. The first laser points to the base of the building and the second laser points to the top of the building. The first laser beam has an angle of depression of 36° and is 155.7 feet long. The second has an angle of elevation of 32° and is 148.6 feet long. How tall is the office building? How far apart are the apartment complex and the office building? Round your answers to the nearest foot.

Answers

Answer:

a. 170 ft b. 126 ft

Step-by-step explanation:

a. How tall is the office building?

The two laser lights with the length of the taller office building, L form a triangle with sides 155.7 feet, 148.6 feet and L with angle 36° + 32° = 68° facing the taller office building.

We use the cosine rule to find the length of taller office building.

So, L² = 155.7² + 148.6² - 2(155.7)(148.6)cos68°

L² = 24242.49 + 22081.96 - 46,274.04(0.3746)

L² = 46324.45 - 17334.56

L² = 28989.89

L = √28989.89

L = 170.26 ft

L ≅ 170 ft

b. How far apart are the apartment complex and the office building?

Using one of the lights, the distance between the buildings, d, the laser light(being the hypotenuse side) and the building (being the opposite side)form a right angled triangle.

So, using the 155.7 feet light at 36 angle,

cos36 = d/155.7

d = 155.7cos36

d = 155.7(0.8090)

d = 125.96 ft

d ≅ 126 ft
