Answer:

a = 60°/2 = 30°

b = 84/2 = 42°

c = (100+60)/2 = 80°

d = 360-100-60-84 = 116°

If the measure of an acute angle is represented by x, then the measure of its complement
Luba_88 [7]

Answer:

always true

Step-by-step explanation:

complement equals that angle plus another one adds to 90. If you know that it's less than 90 degrees, then you subtract it from 90 to get the other angle which is the complement. Hope this helps!

Solve the given system of equations <br> 2x+8y=5<br> 24x-4y=-15
oee [108]

The value of x and y is y= 3/4 and x= -1/2

<h3>What is equation?</h3>

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

Given equations:

2x+8y=5........(1)

24x-4y=-15...........(2)

Multiply equation (1) by 12, we get

24x + 96y = 60.....(3)

From (2) and (3), we get

-4y-96y= -15-60

-100 y= -75

y= -75/-100

y= 3/4

and 2x+8y=5

2x + 8 (3/4) =5

2x + 6 = 5

2x= -1

x= -1/2

Question mark 1: Match the triangle to correct function and answer
postnew [5]

Answer:

Triangle 1 - m\angle A = 58^{\circ}, hypotenuse = 16

x \approx 8.479

Triangle 2 - m \angle A = 44^{\circ}, adjacent leg = 18

x \approx 17.382

Triangle 3 - m\angle A = 49^{\circ}, opposite leg = 12

x \approx 15.900

Step-by-step explanation:

Each triangle is solved by means of trigonometric relations:

Triangle 1 - m\angle A = 58^{\circ}, hypotenuse = 16

\cos 58^{\circ} = \frac{x}{16}

x = 16\cdot \cos 58^{\circ}

x \approx 8.479

Triangle 2 - m \angle A = 44^{\circ}, adjacent leg = 18

\tan 44^{\circ} = \frac{x}{18}

x = 18\cdot \tan 44^{\circ}

x \approx 17.382

Triangle 3 - m\angle A = 49^{\circ}, opposite leg = 12

\sin 49^{\circ} = \frac{12}{x}

x = \frac{12}{\sin 49^{\circ}}

x \approx 15.900
