Answer:
45
Step-by-step explanation:
Set up ratios for 2 similar triangles:
20/28=x/x+18
Cross multiply
28x=20x+360
8x=360
x=45
Answer:
For question 2 :
1 <
2>
3=
Step-by-step explanation:
Basically those triangle arrow things are called 'greater than signs'
So , you need to say which number is bigger than the other or if they are equal. For example :
3>1
1<7
1=1
Answer:
The third angle of the triangle is 70°.
Step-by-step explanation:
The two angles of a triangle (say Δ ABC) are given to be 30° and 80°.
We have to find the third angle.
Let us assume that ∠ A = 30° and ∠ B = 80°, then we have to find ∠ C.
Now, we know that, ∠ A + ∠ B + ∠ C = 180° {Property of a triangle}
⇒ 30° + 80° + ∠ C = 180°
⇒ ∠ C = 180° - 30° - 80° = 70°
Therefore, the third angle of the triangle is 70°. (Answer)
Hence, the correct option is "The 1990s basketball player did better than the current basketball player because his z-score is higher."
