Answer:

Step-by-step explanation:

For this triangle, since the angle is included between 2 given sides, the formula will be:

A =\frac{1}{2}ab*ac*sin(angleA)

Putting values where they belong:

A=\frac{1}{2}(10)(12)sin72

Do all that in your calculator (in degree mode, NOT radian!) to get

A = 57.1 square cm

klio [65]

Answer:

264,666.

Step-by-step explanation:

We have been given that a number has seven digits.

All digits are 6 except the hundred-thousands' digit.

Hundred thousands: 100,000.

The hundred thousand's digit is 2, so its value would be 200,000.

We have been given that thousands's digit is 4, so its value would be:

4 thousands: 4,000

The number with given hundred thousand's and thousands's digit would be 204,000.

Since all digits are 6 except the hundred-thousands' digit, therefore, our number would be 264,666.

Anastaziya [24]
So a diver went 25.65 ft BELOW so it's negative.
then he went 16.5 ft further down, so that's negative also.
he then rose 12.45 ft, so that's positive.
so the expression is: -25.65+-16.5+12.45, the answer is 23.7
