Can you answer it pls and by the way i am in 5th grade
timofeeve [1]

Step-by-step explanation:

3×3 = 9, so it's greater than 3

3×4/3 = 4, so it's greater than 3

3×5/5 = 3, so it's equal to 3

3x4/9 = 4/3, so it's less than 3

3x5/6 = 5/2, so it's less than 3

An angle measures 20° more than the measure of its supplementary angle. What is the measure of each angle?
nevsk [136]

Supplementary angles sum to 180 degrees.

So if one angle is 20 degree more than the other...

x+(x+20)=180

2x+20=180

2x=160

x=80

x+20=100

answer: 80° and 100°

Find the slope of the line joining the points (-1,5) and (6,-2). Also find the equation of that straight line. Find the intercep
Nesterboy [21]

The slope of the line joining the points (-1,5) and (6,-2) is -1

x + y = 4 is the equation of line

x intercept is (-4, 0)

y intercept is (0, 4)

<em><u>Solution:</u></em>

Given that,

Points are (-1,5) and (6,-2)

<em><u>The slope of line is given as:</u></em>

m = \frac{y_2-y_1}{x_2-x_1}

From given,

(x_1, y_1) = (-1, 5)\\\\(x_2, y_2) = (6, -2)

Substituting the values we get,

m = \frac{-2-5}{6+1}\\\\m = \frac{-7}{7}\\\\m = -1

Thus slope of line is -1

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c -------- eqn 1

Where,

m is the slope

c is the y intercept

Substitute m = -1 and (x, y) = (-1, 5) in eqn 1

5 = -1(-1) + c

5 = 1 + c

c = 4

Substitute m = -1 and c = 4 in eqn 1

y = -x + 4

In standard form,

x + y = 4 is the equation of line

<em><u>Find x intercept:</u></em>

Substitute y = 0

x + 0 = 4

x = -4

Thus x intercept is (-4, 0)

<em><u>Find y intercept:</u></em>

Substitute x = 0

0 + y = 4

y = 4

Thus y intercept is (0, 4)

Find the area of the isosceles triangle. please help thanks
fiasKO [112]

Answer:

1080 m^2 Don't submit m^2 in your answer.

Step-by-step explanation:

Givens

The catch is to find h

To do that, use a^2 + b^2 = c^2

a b and c are in the same 1/2 triangle.

a = 48/2 = 24 m

b = h = ?

c = 51 meters

Solution

a^2 + b^2 = 51^2                      Substitute for b^2 = h^2

24^2 + h^2 = 51^2                   Expand 24^2 and 51^2

576 + h^2 = 2601                    Subtract 576 from both sides

h^2 = 2601 - 576

h^2 = 2025                              Take the square root of both sides

h = 45

Area

Area = 1/2 b * h

Area = 1/2 48 * 45

Area = 1080

Remark

Notice that to find h you only use 1/2 of 48 because that is the base of the right triangle.

To find the area, you need to use all of 48 because 48 is the full length of the base.
