Answer:

see explanation

Step-by-step explanation:

Calculate the length using the distance formula

AB = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(4,3) and (x₂, y₂ ) = B(- 2, 1)

AB = $\sqrt{(-2-4)^2+(1-3)^2}$

= $\sqrt{(-6)^2+(-2)^2}$

= $\sqrt{36+4}$

= $\sqrt{40}$

= $\sqrt{4(10)}$ = $\sqrt{4}$ × $\sqrt{10}$ = 2 $\sqrt{10}$ ← exact length

In the figure at the right what is m < 1 if m < 3= 70 degrees

Arturiano [62]

<h2>○=> <u>Correct option</u> :</h2>

$\color{plum}\tt\bold{(D) \: 70}$

<h3>○=> <u>Steps to derive correct option</u> :</h3>

Angle 1 and angle 3 are vertically opposite angles.

We know that :

▪︎ Vertically opposite angles are always equal.

Which means :

Angle 1 = Angle 3

Thus, the measure of angle 3 = 70°

▪︎Therefore, the correct option is (D) 70

Please help me, I am so confused. Thanks

Answer:

c. 80

Step-by-step explanation:

cos x = sin(x-70)

cos x = cos [90-(x-70)]

cos x = cos (90-x +70)

cos x = cos 160 -x

x= 160-x

2x = 160

x =80
