Can someone help me part 2

Otrada [13]

Step-by-step explanation:

y = ¼x + 2

m1 = ¼

m of line perpendicular = m2

the formula is : m1×m2 = -1

=> m2 = -1 ÷ m1

= -1 ÷ ¼ = -4

so, the equation is :

y = -4x - 7 (option A)

Find the sine of ∠U. A)48/55 B)48/73 C)55/48 D)55/73

charle [14.2K]

Answer:

D) 55/73

Step-by-step explanation:

The question is on trigonometry. Sine of an angle is obtained using the SOH of SOHCAHTOA formula of trigonometry. SOH is an acronym for sine, opposite and hypotenuse. Sine of an angle is obtained from the ratio of opposite and hypotenuse of a given triangle. Thus, SOH

is denoted as stated below.

$sine \: \beta = \frac{opposite}{hypotenuse}$

Hence, given the above triangle,

$sine \: of \: angle \: u = \frac{ |bc| }{ |ab| } = \frac{55}{73}$

Therefore, the sine of angle u = 55/73 (D)
