Answer:
angle c = 83 degrees
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral add up to 180 degrees.
According to the rule, <D and <B add up to 180° and same for <A and C.
This means that the sum of (x + 100) and (3x) equal 180.
Therefore (x + 100) + (3x) = 180 →
4x + 100 = 180
–100 –100
4x = 80
÷4 ÷4
x = 20.
Since x = 20, <A = 5x – 3 = 5(20) – 3 = 97.
Since <A + <C = 180.
97 + <C = 180 → 97 + <C = 180
–97 –97
<C = 180 – 97 = 83°

Step-by-step explanation:
Given that :
24 / 18 = 4 / 3 = 1.333
Comparing the options solutions for the options given :
3/9 ÷ 2/8 = 3/9 * 8/2 = 24 / 18 = 1.333
4/9 ÷ 2/6 = 4/9 * 6/2 = 24/18 = 1.333
5/6 ÷ 3/4 = 5/6 * 4/3 = 20 / 18
8/3 ÷ 6/3 = 8/3 * 3/6 = 24 / 18 = 1.333

Can anyone help ? I’m bad at math
Answers
Answer:
Step-by-step explanation:
First you need the third angle (C).
<C + 89 + 45 = 180 All triangles = 180 degrees. Combine the left terms.
<C + 134 = 180 Subtract 134 from both sides
<C = 180 - 134
<C = 46
Next, Let BA = x
x/Sin(46) = 15/Sin(89)
x = 15*sin(46) / Sin(89)
Sin(46) = 0.7193
Sin(89) = 0.9998
x = 0.7193 * 15 / 0.9998
x = 10.7911
Note
When you are studying this material, you should note 2 things.
The first is that you are dealing with 2 ratios that are equal to each other.The second is, the side is always opposite the angle in the triangle. The two are connect. Side c = 15. It is opposite the 89o angle.What are the coordinates of A, B, and C after a translation to the right by 4 units and up 1 unit? Plot these points on the grid, and label them A′, B′ and C′.
