To find the hypotenuse of a right triangle you can use the Pythagorean theorem. (a² + b² = c²) Using the measurements provided we can solve like this.


Both a² & b² = 7²


7 x 7 = 49


49 + 49 = 98


Now we need to find the square root of 98 (c²) to get our answer.


9.9 x 9.9 = 98.01 or about 98


The measurements for the tirangle are 7 units, 7 units, and 9.9 units.


Hope this helps!

<u>Answer:</u>

9.89 units

<u>Step-by-step explanation:</u>

We are a given a right angles triangle which has side lengths 7 units each (of the perpendicular and the base) and we are supposed to find the length of the hypotenuse.

We can find the length of the hypotenuse by using the Pythagoras Theorem:

a^2= b^2+c^2

where a is the hypotenuse and b and c are the perpendicular and base.

a^2=7^2+7^2\\\\a^2=49+49\\\\a^2=98\\\\\sqrt{a^2} =\sqrt{98} \\\\a=9.89

Therefore, the length of the hypotenuse id 9.89 units.

Find the area of the trapezoid.<br> Answer options: 8sqrt2, 4sqrt3, 12.0, 16sqrt2
Elis [28]

Answer:

=  8sqrt2

Step-by-step explanation:

Area of a trapezium is given by the formula;

1/2(a+b)h ;

Where a and b are the parallel sides and h is the perpendicular height.

a = 3 cm, b= 5 cm

To get; h, we use the Pythagoras theorem;

h² = 3² - 1²

   h² = 8

h = √8

  = √4√2

 = 2√2

Thus;

Area = 1/2(3 +5) 2√2

         = 1/2 ×8 × 2√2

       <u>  = 8√2 cm² or  8sqrt2 cm²</u>

How do I find X in this problem
Alona [7]

Answer: x = 16°

Step-by-step explanation:

  • This is a right triangle, which means all angles add up to 180°.
  • One of the angle is already determined to be 90°, that means the sum of the other two angles must also be 90° in order to meet a total of 180°.

This means (x+26)° + 3x° = 90°.

Solve for x:

x + 26 + 3x = 90

x + 3x = 90 - 26

4x = 64

x = 64 ÷ 4 = 16°
