Answer:
In triangle AB, A and B are acute angles so. AC and BC are right angles.
Sin A = 10/13
13 is the hypotenuse side and 10 is the opposite side.
To find cos A.
From pythagorean theorem:
Step-by-step explanation:
Answer: 45b^4/32
Step-by-step explanation: First multiply the two fractions
15b^3y(3b)/8y x 4
Multiply 3 by 15
45b^3yb/8y x 4
Raise b to power of 1
45(b^1b^3)y/8y x 4
Use power rule to combine exponents
45b^1+3 y/8y x 4
Simplify
45b^4y/32y
Cancel common factor of y
45b^4/32
Answer:
1. 1/4+1/4=2/4=1/2
2. Yes
3. i don't know
4. Yes
Step-by-step explanation:
1. 1+1=2 therefore you get 2/4 or 1/2
2. 2/3 is the reduced form of 4/6
3. i honestly dont know
4. 3/4 is the reduced form of 9/12
AB and CD do not intersect.
HOPE it helps!!!!!!
