Answer:
8.5 cm
Step-by-step explanation:
It was a very easy question if I am wrong so sorry i tried my best to answer this question
3. I think it’s A but 7. I know it’s D for sure
Answer:
x = 8, -8
When taking an absolute value the sign of a number is ignored. Therefore, both 8 and -8 would come out equalling 8.
Answer:
I got x<equal to -11 or x>equal to4
Step-by-step explanation:
x^2+15x+44=0
(x+4)(x+11)=0(Factor left side of equation)
x+4=0 or x+11=0(Set factors equal to 0)
x=−4 or x=−11
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x<−11(Works in original inequality)
−11<x<−4(Doesn't work in original inequality)
x>−4(Works in original inequality)
Answer:
x<−11 or x>−4
Answer:
x=11 degrees,y=6
Step-by-step explanation:
Here, given ΔRWS ≅ ΔTUV
Two triangle are said to be congruent to each other it they have exactly the same three sides and exactly the same three angles.
So, here RW = UT, WS = UV and SR = VT
⇒ 25 = 3y + 7
or, 3y = 25 - 7 = 18
or, y = 18/3 = 6
⇒ y = 6
In ΔTUV
By Angle Sum Property:
∠ TUV + ∠ UVT + ∠ UTV = 180°
or, 90° + 29°+ ∠ UTV = 180°
⇒∠ UTV = 180° - 119 = 61°
Now, by congruence rule: ∠ WRS = ∠ UTV
⇒ (8x - 27)° = 61°
or, 8x = 27° + 61° = 88°
or, x = 88/8 = 11°
⇒ x = 11°
