Answer:
x ≈ 14.7
Step-by-step explanation:
use pythagorean therorem
a^2 + b^2 = c^2
c is hypotenuse and we know the hypotenuse is 21
a^2 + b^2 = c^2
x^2 + 15^2 = 21^2
x^2 + 225 = 441
x^2 = 216
x = √216
x ≈ 14.7
Step-by-step explanation:
x¹²-3x6-x⁴+2x⁴-6x³+2x²-3x⁴+9x²-3x
x¹²-3x6-2x⁴-6x³+11x²-3x
Answer:angle x=5
Step-by-step explanation:
Sum of triangles =180 ,x+90+45+40=180, x+175=180 ,x =5
5/15 = 0.33 cm3 …… that is the answer I think of you can answer mine that would be great
35 would be the answer. 45+35=80 and 45 is 10 more than 35
