Answer:
16, see below :)
Step-by-step explanation:
Hello!
We can use the pythagorean theorem because one of the angles is 90 degrees. According to the theorem, a^2 + b^2 = c^2
a is 12, b is unknown, and c is 20
Now we use the theorem
12^2 + b^2 = 20^2
144 + b^2 = 400
b^2 = 256
b = sqrt(256)
b = 16
Answer:
different
Step-by-step explanation:
different slopes gives one solution
same slopes with different constant has no solution
same slopes and constants has many solutions
Answer:
16 cm2
Step-by-step explanation:
By equa tion of area of triangle: S = 1/2 * height * base
Triangle B: 32 = 1/2 * 8 * x --> x = 8 (cm)
The base of triangle A is half of the base of triangle B so it is 4 cm.
The area of triangle A = 1/2 * 8 * 4 = 16 (cm2)
Step-by-step explanation:
90+48=138
180-138=42
y=42
