Answer:
- The statement is <em>false</em>
- There is<em> no solution</em>
Step-by-step explanation:
Step 1: <em>Collect the like terms</em>
2x+7 = -8x-9+10x
2x+7 = 2x-9
Step 2: <em>Cancel</em><em> </em><em>equal</em><em> </em><em>terms</em><em> </em><em>of</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>equation</em>
2x+7 = 2x-9
7 = -9
Result: The statement is <em>false</em> and there is <em>no solution</em> as 7 is <em>not equal</em> to -9.
I hope this helped ! ;)
Answer:
11.2 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opposite side/ adjacent side
tan 66 = BC/ 5
Multiply each side by 5
5 tan 66 = BC
11.23018387 = BC
Rounding to the nearest tenth
11.2 = BC
Use the Pythagorean theorem:
Let x = the height.
2^2 + x^2 = 7.5^2
Simplify:
4 + x^2 = 56.25
Subtract 4 from both sides:
x^2 = 52.25
Take the square root of both sides:
x = 7.2284 m Round the answer as needed.
I rounded it to about 0.040... I havent done this in a while tho so
