Answer:
Step-by-step explanation:
A.) 2a+4b-c: Replacing a with 2, b with 3 and c with 4, we get:
2(2) + 4(3) - (4) = 4 + 12 - 4 = 12
B.) 6(a+c)-b: Replacing a with 2 and c with 4, we get 6(2 + 4) - 3.
The work inside parentheses should be done first, resulting in 6(6) - 3.
This comes out to 33.
Answer:
8
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle
7x - 4 + 9x + 4 = 128° add like terms
16x = 128 divide both sides by 16
x = 8
Push yourself through it u can do it
Answer:
68°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relation between the angle's adjacent side and the hypotenuse is ...
Cos = Adjacent/Hypotenuse
This means ...
cos(B) = a/c
B = arccos(1/√7) ≈ 68°
