Answer:
1,3,21,23,35 odd
Step-by-step explanation:
those aren't prime
Divide 29 by 5 which equals 5 r4. So, the answer is 5 wholes and 4/5
Answer:
1 11/21
Step-by-step explanation:
6/7 + 2/3 = 32/21
32/21 simplified is 1 11/21
Answer:
y ≈ 32.0°
Step-by-step explanation:
Since the triangle is right use the sine ratio to find y
sin y = 
= 
, thus
y = 
( ) ≈ 32.0° ( nearest tenth )
The formula you need to know is that the side opposite of the 30° angle is always half the hypotheneus. For example in question 2 X should be 6 since 3 is opposite side of the angle 30°. In a 45 45 90 triangle, it is important to know that the straight sides are always the same length (since they are the same angle). For example in question 9, v is also 9√2.
When you have two sides, you can figure out the third side with a² + b² = c² since they are all right triangles. Good luck
