Answer:

26

Step-by-step explanation:

The interior angles of triangles always add up to 180. That means that you can just add 64 to 90, which equals 154. Then subtract 154 from 180, which then equals 26.

Hope that this helps!

Answer:

26

Step-by-step explanation:

Given Angles=90° and 64°

We know that in a triangle

\boxed{\sf Sum\:of\:angles=180°}

\rm \rightharpoonup \: 90 + 64 + x = 180 \\  \rm \rightharpoonup \: 154 + x = 180 \\  \rm \rightharpoonup \: x = 180 - 154 \\  \rm \rightharpoonup \: x = 26

79=11x+13 <br> Solve each equation by using the properties of equality and justify each step
neonofarm [45]

Solution: X=6

Detailed explanation:

In this problem we're asked to find "x" or the unknown.

The first step is to subtract 11x from both sides.

---\mapsto\boldsymbol{-11x+79=13}

Next, subtract 79 from both sides.

---\mapsto\boldsymbol{-11x=-66}

To finish this off, divide both sides by -11.

---\mapsto\boldsymbol{x=6}

Voila! There's our answer!

What is the value of x in a 45-45-90 triangle and the hypotenuse is 4?
Temka [501]

9514 1404 393

Answer:

  x = 2√2 ≈ 2.83

Step-by-step explanation:

The side length of an isosceles right triangle is 1/√2 times the hypotenuse length. If x is the side length, then ...

  x = 4/√2 = 4(√2)/2

  x = 2√2 ≈ 2.83

__

You have not specified the form of the answer. Sometimes an exact answer (2√2) is required. Sometimes the answer is required to be rounded to tenths or hundredths.
