Hey! Hope this helps: Angles of a triangle add up to 180°, so doing the equation 180-angle1-angle2=angle3 and plugging in your numbers, you get 180 - 28 - 37 = 115°.

It would be 115 because you do 28+37 which equals 65. The you do 180-65=115.

Lori needs more than 250 signatures to run for the position of class president for her middle school. She already has 75 signatu
olga55 [171]

Answer:

75 + 25d > 250

d > 7

Step-by-step explanation:

Number of signatures needed : > 250

Amount of signatures ready = 75

Exoected number of signatures per day = 25

Number of days, d, needed signatures will be collected ;

Number of ready signatures + (expected number of signatures per day * number of days) > number of signatures needed

Mathematically,

75 + 25d > 250

25d > 250 - 75

25d > 175

d > 175 / 25

d > 7

Enter the value of a and b that complete the sum: 3/x + 5/x^2 = ax+b/x^2
Aleksandr [31]

Answer:

a=\frac{3}{x^{2} }

b=5

Step-by-step explanation:

we are given

\frac{3}{x} }+\frac{5}{x^{2} }=ax+\frac{b}{x^{2} }

we will compare both sides of equaion

 \frac{b}{x^{2} }=\frac{5}{x^{2} }

comparing both sides we get

b=5

and

\frac{3}{x} }=ax

a=\frac{3}{x^{2} }

hence

a=\frac{3}{x^{2} }

and   b=5
