Answer:
check explanation
Step-by-step explanation:
so you must find the missing leg. pythagorean theorem is a^2 + b^2 = c
find C and that number, use to find the area of the triangle.
to find area of a triangle, you use this formula- area=1/2bh
Answer:
1. -2x+24
2. 3x+21
3. 5x-17
4. 3x²+12x
5. 18
Step-by-step explanation:
2. 3(x)+3(7)=3x+21
3. 5(x)+5(-4)+3= 5x-20+3=5x-17
4. 3x(x)+3x(4)=3x²+12x
5. 3(10)-12=30-12=18
Radical 2 = 1.4 So 1.4 * 6 = 8.4
a^2 + b^2 = c^2
8.4^2 + 8.4^2 = square root of c
70.56 + 70.56 = 141.12 ≈ 141
Then you must find the square root of 141 which is 11.874 ≈ 11.9
Side a = 8.4
Side b = 8.4
Side c = 11.9
Answer:
85
Step-by-step explanation:
The line of the right measures 65 degrees (I think), an the line on the left measures 150 degrees. So, 150 - 65 = 85 degrees.
