Mathematics
1 answer:
Ulleksa [173]3 years ago
7 0

Answer:

See explanation

Step-by-step explanation:

Part A.

1. Angle 1 and angle with degree measure of 48° are vertical angles (opposite when two lines intersect). Vertical angles are congruent, so angle 1 has measure of 48°.

2. Angles 1 and 2 are same-side interior angles, they add up to 180°, so

m∠2=180°-m∠1=180°-48°=132°

3. Angles 2 and 3 are alternate exterior angles, they are congruent, so

m∠3=132°

Part B. If Elm Street is perpendicular to Main Street and is also perpendicular to Oak Street, then Main street and Oak Street are parallel.

Find the zeros of the function: f(x) = x^2 - 4x - 21
IrinaK [193]

Answer:

x = 7, x = -3

Step-by-step explanation:

We can find the zeros by factoring the equation using the zero product property.

x^2-4x-21 = 0

(x-7)(x+3) = 0

<u>x-7 = 0</u>

x = 7

<u>x+3 = 0</u>

x = -3

Zeros are x=7 and x= -3.

90 points!!! Algebra - Please check these
Korvikt [17]

First picture:

2 and 7 are alternate exterior angles, which when added together need to equal 180 degrees.

Angle 7 = 180 - 146 = 34

Answer is B.34

Second picture:

Angle 8 = 48

Angle 8  + angle 7 = 180

Angle 7 = 180 - 49 =  131

Angle 5 and angle 7 are vertical angle, so angle 5 = angle 7 = 131

Angle 6 is a vertical angle to angle 8 so = 49

Angle 1 = angle 5 = 131

Angle 2 = angle 6 = 49

Angle 3 = angle 7 = 131

Angle 4 = angle 8 = 49
