Answer:
Step-by-step explanation:
The longest side is opposite the largest angle, and the shortest is opposite the smallest one.
The largest angle lies opposite the longest side, and the smallest is opposite the smallest side.
Q1.
Calculate m∠Y.
We know: Measures of angles of triangle add up to 180°.
m∠Y + m∠W + m∠X = 180°
Substitute given angles:
m∠Y + 51° + 90° = 180°
m∠Y + 141° = 180° <em>substitute 141° from both sides</em>
m∠Y = 39°
39° < 51° < 90° → XW < XY < YW
Q2.
RQ < PR < PQ → ∠P < ∠Q < ∠R
Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
Hope this helps :)
Answer:
1.84metres
Step-by-step explanation:
convert 76cm to metres
76/100=0.76m
convert 8cm to metres
8/100=0.08m
therefore we have,
1+0.76+0.08=1.84metres
if they're both even, divide by two. rational numbers presume reduced fractions. Dividing rational numbers. If two numbers you want to divide, flip the 2nd and multiply.
