Answer:
Area of rhombus is 105.84 cm².
Step-by-step explanation:
Area of rhombus is given by
- Area = diagonal ¹ × diagonal ² / 2
- = 8.4 + 8.4 × 6.3 + 6.3 / 2
- = 16.8cm × 12.6 cm /2
- = 211.68 cm²/2
- = 105.84 cm²
Answer:
Area = 20 ft²

9514 1404 393
Answer:
(b) tan B = 8/6
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant relationships:
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
Then angle B is involved in tangent and cosine relationships this way:
tan B = 8/6 . . . . . . matches 2nd choice
cos B = 6/10 . . . . . matches no choices
_____
<em>Additional comment</em>
Both of the offered cosine choices give a cosine value that is greater than 1. The cosine of a real angle is never greater than 1, so those can be rejected immediately.
Answer:
3375 feet cube
Step-by-step explanation:
Given :
side of cube = 15 feet
Formula used :
Volume of cube , v = a^3
Solution :
Volume of cube
= a^3
= 15^3
= 15*15*15
= 3375 feet cube
