Answer:
Step-by-step explanation:
area πr²=28.26
r²=28.26/π
r=√(28.26/π)≈ 9cm
Answer:
z+42+42=180
Step-by-step explanation:
Since it is an isosceles triangle, the two base angles are the same and remember all the angles add to 180. So use this equation:
z+42+42=180
If you need to find z, it is 96.
Check: 96+42+42=180
Sin^2(x), it’s a sin graph with all positive values which could indicate that it’s squared
7x^4 + x^3 – 3x^2 + 5x – 2
