The length of the hypotenuse would be :

h^2 = 2 (11)^2 

h^2 = 242

h = \sqrt{242}

h = 15.6 cm

So the answer would be option A.

hope this helps

 <span>If there is a hypotenuse, the triangle is a right triangle. From the Pythagorean Theorem: 

c^2 = a^2 + b^2 [the square of the hypotenuse is the sum of the squares of the other two sides] 

c^2 = 11^2 + 11^2 = 121 + 121 = 242 

c = sqrt(242) = 15.56 cm (rounded)</span>

If one pair of adjacent sides of a parallelogram is congruent, then the parallelogram must be a __________.
lubasha [3.4K]

It must be a rhombus, because that's the parallelogram with all sides equal.

It could be a square, but it doesn't have to be.  A square is a rhombus
with special angles.

Please guys I am begging you to help me! This was due yesterday and I need help! SO please help!
jeka57 [31]

Answer:

  • Q3. 12 units
  • Q4. 6.33 units
  • Q5. 66.19°

Step-by-step explanation:

Q3

DE and DF are legs and EF is hypotenuse

  • DE = √EF² - DF²
  • DE = √13² - 5² = √169 - 25 = √ 144 = 12
  • DE = 12 units

Q4

PR is opposite side of angle Q and RQ is adjacent side

  • tan 54 = PR/RQ
  • tan 54 = PR / 4.6
  • PR = 4.6tan 54
  • PR = 6.33 units

Q5

As previous question, using tan as BC is opposite and AC is adjacent leg of angle A

  • tan A = 6.8/3
  • tan A = 2.266
  • A = arctan (2.266)
  • A = 66.19°

Andrew [12]

Answer:

40%

Step-by-step explanation:

If there are 1200 students in the school and 720 of them are boys that means 480 of them are girls.

I like to do cross multiply and divide so the equation for that would be  480/120 = ?/100

if you cross and multiply 480 by 100 you will get 48000 then if you divide that by 1200 you will get 40 as your missing value.

Im basically just saying 480/1200 = 40%

If you need further help there are plenty of you tube videos on how to cross  multiply and divide

Hope this helps

Answer:

1\frac{1}{9}  gallons of paint

Step-by-step explanation:

paint =

2/3 ---- 3/5

x ----  1

x = \frac{\frac{2}{3} }{\frac{3}{5} } =\frac{(2)(5)}{(3)(3)} =\frac{10}{9}

x=1\frac{1}{9}

Hope this helps
