Answer:

$\boxed {\tt Yes}$

$\boxed {\tt The \ 3 \ angles \ add \ to \ 180 \ degrees}$

Step-by-step explanation:

The interior angles of a triangle must add to 180 degrees.

Let's add the three angles we are given and see what the sum is.

The three angles are 127, 38, and 15

Add them together.

127+38+15=180
3 angles = 180 degrees

The three angles equal 180 degrees, therefore they can create a triangle.

Yes, 3 triangles have 180 degrees because the interior angles of a triangle must add to 180 degrees.

step 1

Find the measure of angle 1

REmember that the sum of the interior angles in any triangle must be equal to 180 degrees

In the triangle ABC

90+58+<1=180

148+<1=180

<1=180-148

<1=32 degrees

step 2

Find the measure of angle 2

we know that

<2=<1 -----> bt vertical angles

<2=32 degrees

step 3

Find the measure of angle 3

REmember that the sum of the interior angles in any triangle must be equal to 180 degrees

In the triangle CDE

32+108+<3=180

140+<3=180

<3=180-140

<3=40 degrees

Translate the phrase "in 3 years" into algebraic terms

Semenov [28]

Answer:

In three years can be into algebraic terms as: 3 + x. Where 'x' comes to be today's age.

For example, my age in three years will be:

If I'm 24 years right now, My age in three years = 3 + x ⇒ My age in three years = 3 + 24 = 27.

Answer:

$\boxed{\sf sin\ C =\frac{40}{41}}$

Step-by-step explanation:

We need to find out the value of sinC using the given triangle . Here we can see that the sides of the triangle are 40 , 41 and 9 .

We know that the ratio of sine is perpendicular to hypontenuse .

$\sf\longrightarrow sin\theta =\dfrac{ perpendicular}{hypontenuse}$

Here we can see that the side opposite to angle C is 40 , therefore the perpendicular of the triangle is 40. And the side opposite to 90° angle is 41 . So it's the hypontenuse . On using the ratio of sine ,

$\sf\longrightarrow sinC =\dfrac{ p}{h}\\\\\sf\longrightarrow sin\ C =\dfrac{AB}{AC}$

Substitute the respective values ,

$\sf\longrightarrow \boxed{\blue{\sf sin\ C =\dfrac{40}{41}}}$

<u>Hence the required answer is 40/41.</u>

A drama club made $3,200 from a school play. Seventy-five percent of that amount came from ticket sales. Identify the values of

NISA [10]

Answer:

75%

Step-by-step explanation:

For this case, the first thing we will do is name variables:

a: percentage from ticket sales

b: ticket sales

We have then:

a = 75%

b = (0.75) * (3200) = $ 2400

Answer:

a = 75%

b = (0.75) * (3200) = $ 2400

The amount of ticket sales is $ 2400.
