Answer:
A = pi * r^2 = pi * 5^2 = 25*pi = 78.54 in²
Answer:
z =
or - 0.4
Step-by-step explanation:
8+2z = 6 - 3z
2z = 6 - 8 - 3z
2z + 3z = - 2
5z = -2
z =
or - 0.4
Answer:
C. 10in 24in 26in
Step-by-step explanation:
Right Scalene Triangle
Side a = 24
Side b = 10
Side c = 26
Angle ∠A = 67.38° = 67°22'48" = 1.17601 rad
Angle ∠B = 22.62° = 22°37'12" = 0.39479 rad
Angle ∠C = 90° = 1.5708 rad = π/2
Area = 120
Perimeter p = 60
Semiperimeter s = 30
Height ha = 10
Height hb = 24
Height hc = 9.23077
Median ma = 15.6205
Median mb = 24.5153
Median mc = 13
Change into an improper fraction. 2247/10 then divide. So, 224.7. Or since you know 7/10 is 0.7 just add 224
Answer:
x = 8
Step-by-step explanation:
Since the triangle is equiangular then the 3 angles are congruent and of measure 60°.
Equate any of the 3 angles to 60 and solve for x, that is
7x + 4 = 60 ( subtract 4 from both sides )
7x = 56 ( divide both sides by 7 )
x = 8
