Answer:
b) 12.6 inches
Step-by-step explanation:
tangent is the ratio of the side opposite over adjacent, so if we let x= length of the opposite side, 1.40=x/9, x=12.6 inches
2 corners are both 45 degrees, meaning that they are both the same length.
For this we use the pythagorean theorem, but a bit modified:
a^2 + a^2 = c^2
2a^2 = 256
Solve for a:
a^2 = 128
a = 8 √2
One leg is equal to √128 or 8 √2.
Answer is 28
y+z=4 => y=4-z
yz=3 => (4-z)z=3
=> z^2-4z+3=0
=> z=1 y=3 OR z=3 y=1
=>y^3 + z^3 =3^3+1=28
Answer:
38°
Step-by-step explanation:
All triangles have a sum of 180°
180 - (119 + 23) = missing angle
180 - (142) = missing angle
38 = missing angle
So, the missing angle has a measurement of 38°
