Angle 2 is 110 degrees. Allen claims that we do not have enough information to solve for angle 1. Is he correct? Why or why not?

devlian [24]

Allen's claim that we do not have enough information to solve for angle 1 is incorrect

<h3>How to calculate the measure of angle 1</h3>

Given that:

Angle 2 = 110 degrees

Angle 1 and angle 2, are the only angles on the straight line.

So, we have:

$\angle 1 + \angle 2 = 180$

Substitute 110 for angle 2

$\angle 1 + 110 = 180$

Subtract 110 from both sides

$\angle 1 = 70$

The measure of angle 1 is 70 degrees.

So, we can conclude that Allen's claim is incorrect

Simplify the expression 11x − (2x2 + 8x).

34kurt

$11x - (2x^2 + 8x)$

$11x-2x^2-8x$

$(11x-8x)-2x^2$

$3x-2x^2$

Show that the points A(-1,2), B (5,2) and C (2,5) are the vertices of an isosceles triangle. Find the area of ∆ABC

EastWind [94]

Answer:

the area of ∆ABC = 9

Step-by-step explanation:

$CA=\sqrt{\left( -1-2\right)^{2} +\left( 2-5\right)^{2} } = \sqrt{18} =3\sqrt{2}$

$CB=\sqrt{\left( 5-2\right)^{2} +\left( 2-5\right)^{2} } = \sqrt{18} =3\sqrt{2}$

<em>Since</em> CA = CB <em>then</em> A(-1,2), B (5,2) and C (2,5) are the vertices of an isosceles triangle.

Area calculation:

Let The point H be the midpoint of side AB

$x_{H}=\frac{-1+5}{2} =2\\y_{H}=\frac{2+2}{2} =2$

Then

H(2 , 2)

therefore,

$CH=\sqrt{\left( 2-2{}\right)^{2} +\left( 2-5\right)^{2} } =3$

Finally,

$\text{the area of triangle ABC} =\frac{\text{CH} \times \text{AB} }{2} =\frac{3\times 6}{2} =9$

For a car moving at a constant speed, the distance traveled varies directly with the time spent driving. If such a car travels 5

kaheart [24]

Well if we have 180 miles in 9 hours then by division we can work out that in 1 hour the car travels 20miles. so to get to 140 from 20 we times by 7 so we do the same to the hours which would be 7 hours
