Questions 1, 2, and 3. Help!

Answer:

1. 90      2. 130       3. 55

Step-by-step explanation:

Every triangle when you add all the angles will = 180 degrees for this you add the 2 angles that you have and subtract it from 180

1.   35+55+ C = 180

90 = 180

C = 90

2. 25+25+C = 180

50 + C = 180

C = 130

3. 62 + 63 + C = 180

125 + C = 180

C = 55

Answer:

Step-by-step explanation:

sum of all the angles of triangle = 180

1) ∠1 + ∠2 + ∠3 = 180

35 + 55 + ∠3 = 180

90 + ∠3 = 180

       ∠3 = 180 -90

            ∠3 = 90

If one angle is 90, then, it is a right angled triangle.

2) 25 + 25+ ∠3 =180

        50 + ∠3 =180

             ∠3 =180 -50

       ∠3 = 130

If two angles are equal, then it is an isosceles triangle.

3) 62 + 63 + ∠3 =180

             125 +∠3=180

                     ∠3 = 180-125

                     ∠3 = 55

All the angles are different, so it is a scalene triangle

On a coordinate plane, point B(–6, 1) is translated to B prime(–3, –2). Indira uses these steps to find a rule to describe the translation.

Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b):

B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)

Step 2
Write two equations:
Negative 6 + a = negative 2. 1 + b = negative 3.

Step 3
Solve each equation:
Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.

Step 4
Write the translation rule:
(x, y) right-arrow (x + 4, y minus 4)

Which corrects Indira’s first error?
Indira should have substituted B (negative 6, 1) right-arrow B prime (negative 3 + a, negative 2 + b) = B prime (negative 6, 1) in Step 1.
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Indira should have solved the equations to find that a = negative 8 and b = negative 2 in Step 3.
Indira should have written the translation rule (x, y) right-arrow (x minus 4, y + 4) in Step 4.
