The image I saw was a paper with 90° edges. the 90° was cut into 2, 75° and x.
x = 90° - 75° = 15°
Interior angles of a triangle should equal 180°. The other corner of the paper is part of the triangle. It has a measure of 90°
The two angles are 15° and 90°. To find the remaining unknown angle, we deduct the two angles from 180°
3rd angle = 180° - 15° - 90°
3rd angle = 180° - 105°
3rd angle = 75°
No, GCF means greatest common factor, meaning the largest number than can be divided into the number. 2 would be the lowest common factor or LCF.
EX. 200 & 440. In this case the GCF would be 40, but the LCF would be 2 because they are both even numbers
Answer:
x = 5
Step-by-step explanation:
using the sine or cosine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5
