Answer:
sin a=3/5
cos a=4/5
Step-by-step explanation:
<u>sin</u> <u>A</u>
AB(squared)=AC (squared)+CB(squared) AB(squared)=4(squared)+3(squared)
AB (squared)=16+9
AB (you must put a square root over AB)=25(remember 25 is now a square root)
AB=5
sin a=opposite/hypotenuse
=3/5
<u>cos A</u>
cos a=adjacent/hypotenuse
=4/5
Answer: 16 inches
Step-by-step explanation:
The area of a triangle = bh/2
where b = base = unknown
h = height = 5 3/4 inches
Area = 46 inches²
Therefore, 46 = base × 5 3/4 / 2
Cross multiply
46 × 2 = base × 5 3/4
92 = base × 5 3/4
Base = 92 ÷ 5 3/4
Base = 92 ÷ 23/4
Base = 92 × 4/23
Base = 4 × 4
Base = 16 inches
