If the measurment of the angles of a triangle are 3b,2b,and 4b then what is the smallest angle

d1i1m1o1n [39]

Given:

The measurement of the angles of a triangle are 3b,2b,and 4b.

To find:

The smallest angle.

Solution:

According to the angle sum property, the sum of all angles of a triangle is 180 degrees.

$3b+2b+4b=180^{\circ}$ [Angle sum property]

$9b=180^{\circ}$

Divide both sides by 9.

$b=20^{\circ}$

Now,

$3b=3(20^{\circ})=60^{\circ}$

$2b=2(20^{\circ})=40^{\circ}$

$3b=4(20^{\circ})=80^{\circ}$

Therefore, the smallest angle is 40 degrees.

Multiply 13 to both sides to get q by itself

4/9*13=q

this gives you

5.77777778=q

What is the result of isolating y^2 in the equation below (x-2)^2+y^2=64?

natta225 [31]

What is the result of isolating y^2 in the equation below (x-2)^2+y^2=64?

Solution:

We want to isolate $y^{2}$ from the equation $(x-2)^{2} +y^{2} =64$

To isolate $y^{2}$ , we must try to get $y^{2}$ alone

So, We must subtract $(x-2)^{2}$ from both sides

$(x-2)^{2}-(x-2)^{2} +y^{2} =64-(x-2)^{2}$

$0 +y^{2} =64-(x-2)^{2}$

$y^{2} =64-(x^{2}-4x+4)$

Distributing '-' inside parenthesis

$y^{2} =64-x^{2} +4x -4$

$y^{2} =60-x^{2} +4x$
