Atriangle abc has two side lengths of 28 ft. and 24 ft. if angle c is 91°, what's the measurement of angle b

Step-by-step explanation:

Given that in a triangle ABC,  AB = 28, BC = 24 and angle C =91,

We have to find measure of angle B.

Since three measurements are given, we can solve the triangle easily

Use the sine formula for triangles.

Since sum of 3 angles is 180, we calculate B easily

Angle B = 180-(A+C)

= 180-(91+58.98)

=30.02

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
