Step-by-step explanation:

Use SOH-CAH-TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Side a is adjacent to the 29° angle, and 14 is opposite of the 29° angle. So use tangent:

tan 29° = 14 / a

a = 14 / tan 29°

a ≈ 25.3

Side c is the hypotenuse, and 14 is opposite of the 29° angle. So use sine:

sin 29° = 14 / c

c = 14 / sin 29°

c ≈ 28.9

4.. Please help. Is DE←→ perpendicular to FG←→? Why or why not?

olya-2409 [2.1K]

Given:

DE contains the points D(1, -2) and E(3, 4).

FG contains the points F(-1, 2) and G(4, 0).

To find:

Is DE perpendicular to FG.

Solution:

Slope of DE:

$$m=\frac{y_2-y_1}{x_2-x_1}$

Here $x_1=1, y_1=-2, x_2=3, y_2=4$

$$m=\frac{4-(-2)}{3-1}$

$$m=\frac{6}{2}$

m = 3

Slope of FG:

$$m=\frac{y_2-y_1}{x_2-x_1}$

Here $x_1=-1, y_1=2, x_2=4, y_2=0$

$$m=\frac{0-2}{4-(-1)}$

$$m=\frac{-2}{4+1}$

$$m=\frac{-2}{5}$

Two lines are perpendicular if product their slopes are -1.

Slope of DE × Slope of FG

$$=3\times \frac{-2}{5}$

$$= \frac{-6}{5}$

≠ -1

The solution is no, because the product of the slopes is not -1.

Answer:

By factoring

Step-by-step explanation:

4x^2+25=20x then:

4x^2-20x+25=0

factoring:

(2x-5)(2x-5)=0

2x=5, x=2.5
