Answer:

76

Step-by-step explanation:

The sum of the angles of a triangle add to 180

3x+10 + 2x+20 = 140

5x+30=140

-30       -30

5x=110

x=22

3*22=66+10=76

Answer:

76

Step-by-step explanation:

The sum of the angles of a triangle add to 180

40+ 3x+10 + 2x+20 = 180

Combine like terms

70 + 5x = 180

Subtract 70

70+5x-70 =180-70

5x = 110

Divide by 5

5x/5 = 110/5

x = 22

We want to find BCA

BCA = 3x+10

        = 3(22)+10

        = 66+10

         =76

PLEASE PLEASE I NEED HELP ASAP
Sidana [21]
AE = AC = 4

m<CAB = 60 (equilateral triangle)
m<CAE = 90 (square)

m<BAE = 150 (= 60 + 90)

Triangle BAE is isosceles since AB = AE;
therefore, m<AEB = m<ABE.

m<AEB + m<ABE + m<BAE = 180

m<AEB + m< ABE + 150 = 180

m<AEB + m<AEB = 30

m<AEB = 15

In triangle ABE, we know AE = AB = 4;
we also know m<BAE = 150, and m<AEB = 15.

We can use the law of sines to find BE.

BE/(sin 150) = 4/(sin 15)

BE = (4 sin 150)/(sin 15)

BE = 7.727

F(x)=2x-3 g(x)=x^2+1 find g(2)
Hitman42 [59]

Answer:

g(2)=5

Step-by-step explanation:

since g(x) is equal to x^2+1, you just plug in the value of 2 for x, to get 2^2+1, and 2 to the power of 2 (also known as 2 squared) is equal to 4, which makes your equation 4+1, which equals 5.
