PLEASE HELP FINDING y IN TRIANGLE AND ROUND TO NEAREST TENTH TRIG!! HELP ASAP APLEASE

Mathematics
1 answer:
polet [3.4K]3 years ago
5 0

Answer:

<em>y = 12.3 cm</em>

Step-by-step explanation:

This is a right triangle, so we can use sin,cos, or tan to solve this.

First, with respect to the angle 35 degrees, we can say "y" is the "adjacent side".

Also, the hypotenuse is given as 15.

<em>Which trig ratio relates adjacent and hypotenuse? That is COS. So we can write and solve the equation below:</em>

<em>Cos(35)=\frac{y}{15}\\y=Cos(35)*15\\y=12.29</em>

<em />

<em>Rounded to 1 decimal place (nearest tenth) , </em>

<em>y = 12.3 cm</em>

Helga [31]

Answer:

The required proof is shown below.

Step-by-step explanation:

Consider the provided figure.

It is given that KM=LN

We need to prove KL=MN

Now consider the provided statement.

KM = LN                     Given

KM = KL+LM              Segment addition postulate

LN = LM+MN             Segment addition postulate

KL+LM = LM+MN      Substitution property of equality

KL = MN                    Subtraction property of equality

The required proof is shown above.

1.y-4.90 = 2.4(x-1) 2. 24x-10y= -25

Step-by-step explanation:

The point-slope form of an equation is written as ;

y-y₁ = m(x-x₁) where the focus is on the slope of the line and a point on the line.

In this case, y-4.90 = 2.4(x-1)

The standard form an equation is written as :

Ax+By=C ,where x and y are variables and A,B and C are integers.

In this case; 24x-10y= -25
