Answer:
you could get y
=
−
1/2
x
−
3
/2
Step-by-step explanation:
Answer:
y = 1/3x + 10/3
Step-by-step explanation:
→ Write gradient into format
y = 1/3x + c
→ Substitute in (5,5)
5 = 5/3 + c
→ Find c
c = 5 - 5/3 = 10/3
→ Finish off
y = 1/3x + 10/3
Answer:
8%
Step-by-step explanation:
The reason why is his grade is 72% right and it increased to 80%.
Subtract 80 from 72 which equals 8.
Answer:
<u>The length of GI is 90.06 units </u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
GH = 60 units
HI = 42 units
∠H = 123°
2. Using the Law of Cosines, we can find the length of GI, this way:
GI² = GH² + HI² - 2 * GH * HI * cos ∠H
Replacing with the real values:
GI² = 60² + 42² - 2 * 60 * 42 * cos ∠123°
GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545
GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545
GI² = 3,600 + 1,764 + 2,746.8
GI² = 8,110.8
GI = √ 8,110.8 = 90.06 units
Hello!
First you have to find the ratio
To find this you put the sides of the triangles in a ratio and simplify it
Make sure you do the same side on each triangle
12 : 8
6:4
3:2
The ratio is 3:2
We do not know all three sides so we can use the SSS postulate
This tells use the answer is the SAS postulate with a ratio of 3:2
The answer is D) SAS; 3:2
Hope this helps!
