I need to know what d=

d = 30

Step-by-step explanation:

All angles in a triangle must add up to 180° so:

35 + 55 + 3d = 180

Step 1 - Simplify:

90 + 3d = 180

Step 2 - Subtract 90 from both sides:

90 + 3d - 90 = 180 - 90

3d = 90

Step 3 - Divide both sides by 3:

Hope this helps!

Step-by-step explanation:

Sum of the interior angles in a triangle is added up to 180°

There fore,

So,

Hope this helps you

Let me know if you have any other questions :-)

a. she will receive a refund of $278.

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
