Answer:
80 degrees
Step-by-step explanation:
an triangle has 180 degress 30 is for angle A so you have 150 left if you put 70 degrees for angle b then you 80 degrees left for angle c. 30+70+80=180
Step-by-step explanation:
180° = 2x + 70 + 4x + 10
180° = 2x + 4x + 70 + 10
180° = 6x+ 80
180 - 80 = 6x
100 = 6x
6x = 100
x = 16.66
x ≈ 17°
Answer:
The smaller number = -1
The larger number = 3
Step-by-step explanation:
Let the smaller number = a
Let the larger number = b
The larger of two numbers is 6 more than 3 times the smaller.
b = 3a + 6........... Equation 1
If the twice the larger number is increased by 3 times the smaller, the result is 3.
2b + 3a = 3........ Equation 2
Hence:
We Substitute 3a + 6 for b in Equation 2
2b + 3a = 3
2(3a + 6) + 3a = 3
6a + 12 + 3a = 3
9a = 3 - 12
9a = -9
a = -9/9
a = -1
b = 3a + 6........... Equation 1
b = 3(-1) + 6
b = -3+ 6
b = 3
Therefore,
The smaller number = -1
The larger number = 3
Answer:
x > -1
Step-by-step explanation:
p = (f o g)(x) = log ((x+4)-3)
p = log (x+1)
so that p has a value,
the value of x + 1 mus be greater than 0
x + 1 > 0
x > -1
so the domain is x > -1
Domain = {x | x > -1, x must real number}
Answer: the key idea of the transformation called a rotation is the moving of the plane a certain angle around a fixed point.
