Answer:65 degrees
Step-by-step explanation: a triangle has 180 degrees.
one angle is 45 degrees and the other is 70
if we add them together we get 115
180-115 is 65
m3 is 65 degrees
The equation for density is:

To help you remember - my teacher told us to remember "We <span>♡ density," and the heart stands for </span>

, or

. Cheesy, but it works!<span>
</span>
Back to the problem:We know the mass if 49g and the volume is 7

, so plug these values into the equation for density:
Answer: The density is 7 g/
Answer:
Hello! answer: 432
Step-by-step explanation:
12 × 8 = 96
12 × 8 = 96
12 × 6 = 72
12 × 6 = 72
8 × 6 = 48
8 × 6 = 48
Then you add them all up so...
96 + 96 + 72 + 72 + 48 + 48 = 432 therefore the surface area is 432 hope that helps!
