prove “if two angles of one triangle are congruent to two angles of a second triangle, the the third angles of the triangles are

arsen [322]

Assume that,

The two angles of one triangle are congruent to two angles of a second triangle.

To prove: The third angles of the triangles are congruent.

Since, two angles of one triangle are congruent to two angles of a second triangle.

Therefore,

$\begin{gathered} \angle C=\angle F \\ \angle A=\angle D \end{gathered}$

Adding these two we get,

$\begin{gathered} \angle C+\angle A=\angle F+\angle D \\ 180-\angle B=180-\angle E\text{ (Using angle sum property of a triangle)} \end{gathered}$

Cancelling 180 on both sides, we get

$\begin{gathered} \angle B=\angle E \\ \therefore\angle B\cong\angle E \end{gathered}$

Hence, if two angles of one triangle are congruent to two angles of a second triangle, the the third angles of the triangles are congruent.

Simplify (2^2•5)^3/2^5•5^8

Kryger [21]

Answer:

$2^{17}$

Step-by-step explanation:

$(2^{2 \times 5})^3/(2^5 \times 5^8)$

$(2^{10})^3/(2^{5+8})$

$2^{10 \times 3}/(2^{5+8})$

$2^{30}/(2^{13})$

$2^{30-13}$

$=2^{17}$

Please help me. I’m not smart.

klio [65]

Answer:

3/4 or 0.75

Step-by-step explanation:

the equation is in slope-intercept form

y=mx+b

where m is the slope and b is the y-intercept.

you have already found the y-intercept to be -2, so now we just have to find the slope.

slope is also known as rise/run. so if we start at the y-intercept of -2, we can rise (go up) 3 units and then run (go over) 4 units until we reach another point on the line.

so the slope is 3/4 which is also equal to 0.75 units
