D) x=90, y=43
This is because sides AB and AC are equal so angles B and C are thus both 47.
Also, since both angles BAD and BAC are equal, and x is likely 90, that must be 180-(90+47)=43.
first one: B)
180 - 35 = 145
second one:
ABC & DEC triangles are identical so:
third one:
Same thing. 22^2+b^2=33^2
484+b^2=1089
b^2=605
b=24.60
Answer:
If you have a die that has 6 sides the expected value of the number rolled is 3.5.
Explanation:
<em>Well 6 divided by 2 is 3 but when you add .5 to 3 it is </em><em>3.5 </em><em>and that makes it even. So the answer is </em><em>3.5</em>
Answer:
x=10. x=-8. x=5. x=10. x=120.
Step-by-step explanation:
If your trying to find x then get x by its self.
3x=2x +10 subtract 2x from both sides
x=10
5x=4x-8 subtract 4x from both sides
x= -8
x +5=2x subtract x from both sides
x=5
3x+10=4x subtract 3x from both sides
x=10
120+5x=6x subtract 5x from both sides
120=x
