Answer:

1) m<2 = 115°

2) m<5 = 83°

3) m<8 = 45°

4) m<4 = 137°

Step-by-step explanation:

When two lines cross over each other, creating four angles, the opposite angles are equal.

So in question one, <1 is equal to <2, the angle opposite it, and so it is 115°.

Similarly, in question two, <5 = <6 = 84°.

In question three, <8 = <9 = 45°.

and in question four, <3 = <4 =137°.

Answer:

1) 115

2) 83

3) 45

4) 137

Step-by-step explanation:

Each problem is asking you to find the missing angle given its vertical angle.

Vertical angles are congruent therefore the angle given is the answer

Just in case that doesn't make sense here you go:

For #1 ∠1 and ∠2 are vertical angles

vertical angles are congruent ( equal to each other ) so if

∠1 = 115° then ∠2 = 115°

For#2 ∠5 and ∠6 are also vertical angles so they are congruent

so if ∠5 = 83° then ∠6 = 83°

For #3 ∠8 and ∠9 are vertical angles so they are congruent

so if ∠8 = 45° then ∠9 = 45°

For #4 ∠3 and ∠4 are vertical angles so they are congruent

So if ∠3 = 137° then ∠4 = 137°

What’s the value of x in the equation bellow?<br> 2x -1= 3-2x

artcher [175]

Answer:

Step-by-step explanation:

✯Hello✯

↪ So first we need to eliminate the smaller value for x by adding 2 to both sides

↪ We then have 4x-1=3

↪ Add 1 to both sides so 4x=4

↪ Divide both sides by 4 and x=1

Henry is making a recipe for biscuits. A recipe calls for 3 /10 kilogram flour and 8 /100 kilogram sugar. If Henry measures corr

fgiga [73]

Answer:

38/100

Step-by-step explanation:

To combine the amounts, add the fractions with a common denominator.

3/10 kilogram flour is 30/100.

8/100 kilogram of sugar.

Both now have the same denominator. Add the numerators to find the total.

30/100 + 8/100 = 38/100

2. Find the value of x and y rounded to the nearest tenth.

SVETLANKA909090 [29]

Using relations in a right triangle, it is found that the values of x and y are given by: x = 24, y = 46.4, given by option a.

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.

The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.

The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

First, we start with the vertical line h that divides y, that is <u>opposite to an angle of 30º, with hypotenuse 34</u>, hence:

sin(30º) = h/34

0.5 = h/34

h = 17.

Then, h is opposite to an angle of 45º, while the hypotenuse is x, hence:

$\sin{45^\circ} = \frac{17}{x}$

$x = \frac{17}{\sin{45^\circ}}$

x = 24.

y is divided into two segments.

The first is the adjacent to the angle of 30º, while the hypotenuse is 34.

The second is adjacent to the angle of 45º, while the hypotenuse is 24.

Then:

$\cos{30^\circ} = \frac{y_1}{34}$

$y_1 = 34\cos{30^\circ} = 29.4$

$\cos{45^\circ} = \frac{y_2}{24}$

$y_2 = 24\cos{45^\circ} = 17$

Then, the value of y is given by:

$y = y_1 + y_2 = 29.4 + 17 = 46.4$ .
