The angular measure L is : 47°
<h3>What are angles?</h3>
Angles are formed when two lines meet.
Analysis:
Firstly, we calculate for m using cosine rule.
=
+
-2(510)(820) cos 20
= 260100 + 672400 -83600(0.9396)
= 146618.56
m =
= 382.9cm
using sine rule to find ∠L
382.9/sin20 = 820/sinL
sinL = 820sin20/382.9
sinL = 820(0.342)/382.9
sinL = 0.732
L = sin inverse of 0.732 = 47°
In conclusion, ∠L is 47°

You can solve it as 3*500+3*80+3*4. It the same as solving it normally, since you're essentially solving it as above (one place value at a time).
If you would like to know a number you can square and the answer is bigger than 400 but smaller than 500, you can calculate this using the following step:
20^2 = 400 < 21^2 = 441 < 22^2 = 484 < 500
There are two correct results: 21 and 22.
Answer:

Step-by-step explanation:
The equation of a line follows the following format

Note m= the gradient of the line or the slope of the line. To find the gradient it is

On this graph the

After finding the gradient we can now find the equation of the line. We can use any point on the line in order to do this, in that case lets use the point (10, 460)


Answer:
x=-2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(x+3)(2)−4=0
4x+12+−4=0(Distribute)
(4x)+(12+−4)=0(Combine Like Terms)
4x+8=0
4x+8=0
Step 2: Subtract 8 from both sides.
4x+8−8=0−8
4x=−8
Step 3: Divide both sides by 4.
4x/4 =-8/4
x=−2
