Answer: Measure of ∠XOB is 110°.

Step-by-step explanation:

Since we have given that

In this rotation , WXY is mapped to CBA.

According to mapping, WXY is mapped to TSR.

So, X is corresponds to S

So, it will form equal angle say ∠1.

Similarly,

TSR is mapped to CBA.

So, S is correspond to B forming equal angle say ∠2.

As shown in the figure.

Now, we have already given that

∠1+∠2=55°

so, ∠1+∠1+∠2+∠2=∠XOB

2(∠1+∠2)=∠XOB

2×55°=∠XOB

110°=∠XOB.

Hence, Measure of ∠XOB is 110°.

If 100% of a number is 15, what is 50% of the number?
anzhelika [568]

Answer:

Let n be the number

100% of a number is 15 is written as: 100% × n = 15

100% = 100 / 100 = 1

Hence

100% × n = n = 15

We now need to find 50% of the number

50% of 15 = (50 / 100) × 15 = 750 / 100 = 7.5

Answer:

the length of the opposite side (x), is 27.2

Step-by-step explanation:

For the given right triangle problem;

the opposite side of the given angle, opp. = 22

the hypothenuse side,  hypo. = x

given angle of the triangle, θ = 54⁰

The length of the opposite side (x), is calculated as follows;

sin \ \theta = \frac{opp.}{hypo.} \\\\sin (54) = \frac{22}{x} \\\\x = \frac{22}{sin(54)} \\\\x = 27.2

Therefore, the length of the opposite side (x), is 27.2

Identify an equation in point slope form for the line parallel to y=1/2x-7 that passes through (-3,-2)
ANTONII [103]

Answer:

Step-by-step explanation:

The point slope form of a straight line is expressed as

y - y1 = m(x - x1)

Where

m represents slope of the line

y1 represents the initial value of y

x1 represents the initial value of x

If two lines are parallel, it means that they have the same slope. From the equation of the given line, slope = 1/2

Therefore,

m = 1/2

x1 = - 3

y1 = - 2

Substituting into the point slope equation, it becomes

y - - 2 = 1/2(x - - 3)

y + 2 = 1/2(x + 3)

The equation is

y + 2 = 1/2(x + 3)
