Answer:

<em>Well, Your best answer will be is </em><em>45° </em><em>Because, Given two sides and the angle in between,  we can calculate for ∠A using the sine law: </em>

<em> </em>

<em>b / sin B = a / sin A </em>

<em> </em>

<em>2.45 / sin 60 = 2 / sin A </em>

<em> </em>

<em>sin A = 0.707 </em>

<em> </em>

<em>A = 45˚ </em>

<em> </em>

<em>Therefore the answer is letter A: 45 </em><em>Good Luck! </em>

Step-by-step explanation:

Thr triangles are similar if any two sides are proportional.

In this, we cannot see any proportional sides, like

DU should be proportional to UT, it is not.

SU should be equal to UE ,it is not.

So, The triangles are not similar.

Hope it helps :)

A line passes through (-1,7)and(2, 10)
kumpel [21]
Slope
m = (y2-y1)/(x2-x1)
m = (10 - 7)/(2 --1)
m = 3/3
m = 1

To find the equation
y = mx + b
m is slope
y = 1x + b
plug in one of the equations to solve for b
10 = 1(2) + b
10 = 2 + b
subtract 2 from both sides
8 = b

The equation is 
y = 1x + 8
or you can write it as
y = x + 8

Hope this helps
