Answer:

The value of x is 41.1 units .

Step-by-step explanation:

You have to use Cosine Rule, cosθ = adjacent/hypotenuse. Then substitute the following values into the formula :

\cos(θ) =  \frac{adj.}{hypo.}

Let θ = 47°,

Let adj. = 28,

Let hypo. = x,

\cos(47)  =  \frac{28}{x}

x \cos(47)  = 28

x =  \frac{28}{ \cos(47) }

x = 41.1 \: units \: (3s.f)

1. What is the measure of angle x? O 60° O 90° O 45° O 30°​
True [87]

Answer:

Angle x= 60°

Step-by-step explanation:

For the triangle HIL, you're going to add 30+90=120

Angles in a triangle add up to 180.

So, therefore,

180-120=60   so angle L must equal 60.

HJ is a straight line and angles in a straight line add up to 180.

180-90=90

Angle JIL is equal to 90.

To find y you add 90+45 which equals 135.

Again, angles in a triangle add up to 180.

180-135=45

So,

y = 45

Now we are told that IJK is a right angle and that we are given that IJL is 45. 45 is half of 90 so LJK must be 45.

To find angle JLK we must add angle L and angle y.

60+45=105

Angles in a straight line add up to 180. So,

180-105=75

75 = Angle JLK

75+45=120

Angles in a triangle add up to 180 so,

180-120= 60

Angle x= 60°

51.75 which is 52 because you tound up so it can carry approximately 52 cars because 828÷16=51.75 so it would be approximately 52

The domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis.

The range is the set of possible output values, which are shown on the y-axis.

In the given graph, it shows that:

Domain (x-values): All reals

Range (y-values): y ≥ 2
