Answer:
45
Step-by-step explanation:
Together, these two angles form a flat line which is 180 degrees
(x + 7) + (4x - 52) = 180
5x - 45 = 180
+ 45 + 45
5x = 225
x = 45
Step-by-step explanation:
003:
To solve this, we'll be using the Pythagorean theorem,
004:
For the next couple questions we'll be using a fun rule called SOHCAHTOA, which stands for Sin (Opposite/Hypotenuse) Cos (Adjacent/Hypotenuse) Tan (Opposite/Adjacent). From this we can see that Tan θ is 8/.
005:
From this rule again, we can tell that sin Ф (Opposite/Hypotenuse) is going to be /15.
Answer:
003:
004: 8/
005: /15
Answer:
100
Step-by-step explanation:
To make a perfect square trinomial, you want to divide the use the following equation to find the missing constant:
when the quadratic is in standard form.
In this case, we would divide -20 by 2 and square it
-20/2 = -10
(-10)^2 = 100
The answer is B (-3).
-2+3n>-14
+2 +2
3n>-12
n>-4
The answer is 8,000 because 19 times 421 equals 7,888 and that estimated is 8,000
