help which one is the answer

Answers

1 : 115 ( add it up )

2 : 180 ( obtuse angle )

3 : 109 ( add it up )

* hope this helps :) *

Answer:

1) 103 degrees

2) 109 degrees

3) 65 degrees

Step-by-step explanation:

1) A line is 180 degrees, so 180 - 77 = 103 degrees. y = 103

2) All the angles in a triangle add up to 180 degrees, so 64 + 45 = 109. 180 - 109 = 135. x = 135

3) same as the last one, 68 + 47 = 115. 180 - 115 = 65. x = 65

Step-by-step explanation:

g(x) = |x|

[tex]1^{st}[/tex] step - shifts right 5 units: g(x + 5) = | x - 5 |

[tex]2^{nd}[/tex] step - shifts up 2 units: g(x + 5) + 2 = | x - 5 | + 2

If a||b m<2=63 and m<9=105 find the measure of each missing angle

Answers

Answer/Step-by-step explanation:

Given, m<2 = 63°; m<9 = 105°, and line a is parallel to b:

a. m<1 + m<2 = m<9 (alternate exterior angles are congruent)

m<1 + 63° = 105° (substitution)

Subtract 63 from each side

m<1 = 105° - 63°

m<1 = 42°

b. m<3 + m<2 + m<1 = 180° (angles in a straight line)

m<3 + 63° + 42° = 180° (substitution)

m<3 + 105° = 180°

m<3 = 180° - 105°

m<3 = 75°

c. m<4 = m<1 (vertical angles are congruent)

m<4 = 42°

d. m<5 = m<2 (vertical angles are congruent)

m<5 = 63°

e. m<6 = m<3 (vertical angles are congruent)

m<6 = 75°

f. m<7 = m<9 (vertical angles are congruent)

m<7 = 105°

g. m<8 = m<6 (alternate interior angles are congruent)

m<8 = 75°

h. m<10 = m<8 (vertical angles are congruent)

m<8 = 75°

i. m<11 = m<4 (alternate interior angles)

m<11 = 42°

j. m<12 = 180° - m<11 (linear pair theorem)

m<12 = 180° - 42° (substitution)

m<12 = 138°

k. m<13 = m<11 (vertical angles are congruent)

m<13 = 42° (substitution)

l. m<14 = m<12 (vertical angles are congruent)

m<14 = 138°

How do i find the measures of each numbered angle ​

Answers

Answer:

The angles of every triangle add up to 180

Step-by-step explanation:

Angle 2=52) Add 71+57=128. 180-128=52

Angle 1= 123) Angle 57 and 1 are supplementary angles which means they add up to 180. So subtract 57 from 180 which will give you 123.

Angle 3= 29) Now that we know that angle 1 is 123, we add 123 and 28 which gives 151. Then subtract 180-151 which equals 29.

This problem was like a pattern. You work with one part at a time and then you unsolve each part :)

The angles in the triangle are as follows;

∠1 = 117 degrees

∠2 = 52 degrees

∠3 = 35 degrees

How to find the angles in a triangle?

A triangle is a polygon with three sides . The sum of angles in a triangle is 180 degrees.

The angles can be found as follows in the triangle.

∠1 = 180 - 57 = 117 degrees(sum of angles in a triangle)

∠2 = 180 - 71 - 57(sum of angles in a triangle)

∠2 = 52 degrees

∠3 = 180 - 28 - 117

∠3 = 35 degrees

Select all angles that MUST be supplementary to 9

Answers

Answer:

Angles supplementary to angle 9 = Angle 10, 7, 5, 1, 4, 3, 15, 12, 24, 22, 20, 19, and angle 16.

Step-by-step explanation:

Use the vertical, and corresponding angles theorem to find congruent angles.

Look for linear pairs (adjacent(next to each other, or share a side) angles that make 180° or a straight angle) from the corresponding angles.

Something is supplementary if it adds to 180 degrees.

The vertical angles theorem states that pairs of opposite angles made by interesecting lines are congruent.

The corresponding angles theorem states that corresponding or angles relative to the same position are congruent if the transversal crosses at least 2 parallel lines.
