Answer: 22 meters
<u>Step-by-step explanation:</u>
Draw a picture of a right triangle and label the height as 30 meters and the hypotenuse as 37 meters. Use the Pythagorean Theorem to find the base (the length of the shadow).
a² + b² = c²
x² + 30² = 37²
x² = 37² - 30²
x² = 1369 - 900
x² = 469
√x² = √469
x = 21.656
x ≈ 22
Answer:
sum of interior angle of triangle is 180°
therefore, 81°+37°+X=180°
118°+X =180°
X=180°-118°
X=62°
k+x=180°
k+62°=180°
k=180°-62°
k=118°
hence proved
OR
the sum of 2 interior angle is equal to a exterior angle,so 81°+37°=k
118°=k

Answer:-5,3
Step-by-step explanation:
Answer:
20 Questions
Step-by-step explanation:
If 15 is 60% of the total number, you can divide 15 by 60 so you can find 1% of the total amount of questions.
15/60=0.25
0.25*100=25 questions.
Deon only got 80% percent right, which can be multiplied.
25*0.8=20
Hope this helped!
