Two interior angles in a triangle measure 101 degrees and 34 degrees. What is the measure of the third angle?

Colt1911 [192]

All the angles in a triangle equal 180 degrees.

So,

101+34+x=180

x= the missing angle.

135+x=180

Subtract both sides by 135.

x= 45

The missing angle equals 45 degrees.

I hope this helps!

EMERGENCY, EMERGENCY, I WILL GIVE BRAINLIEST

First you must distribute the 1/4 to get
: 1/2x^2-3=15
then you have to add three to both sides so it become
: 1/2x^2=18
then divide by 1/2 to get
:x^2 =36
then take the square root to get a final answer of
:x=6

Can you please help me

Slav-nsk [51]

Answer:

Step-by-step explanation:

Hi there!

To answer this, we must set it up as

$3x(2x^4-12x^2+7)$

Now we just use the distributive property to solve.

this becomes $6x^5-36x^3+21x$

I hope this helps!

In the triangle below,<br> y = [ ? ] cm. Round to the<br> nearest tenth.

sattari [20]

Answer:

The answer is

Step-by-step explanation:

Since the triangle is a right angled triangle we can use trigonometric ratios to find y

To find y we use cosine

cos∅ = adjacent / hypotenuse

From the question

y is the adjacent

The hypotenuse is 15

So we have

$\cos(35) = \frac{y}{15} \\ y = 15 \cos( 35 ) \\ y = 12.28728$

We have the final answer as

<h3>12.3 cm to the nearest tenth</h3>

Hope this helps you
