Answer:
9 & 1/4
Step-by-step explanation:
you have 3/4 and you subtract by 10, and since 3/4 is a decimal (0.75) you subtract it by 10 wich gives you 9 & 1/4
Answer:
77 degrees and 90 degrees
The angle d is shown as 90 by the perfect right angle. The angle e has to equal 180 when added to f. So 180-103=77.
Basically you need to find the answer choice that is rational. That way the sum will also be rational.
√7 is irrational as well as π and 0.5050050005...
2/4 is the only rational option.
answer: D
Answer:
57°
Step-by-step explanation:
We can see that LOM is MON + LON so we can set up an equation to find the value of x then substitute that back into MON to find the value of that angle.
→ In equations its important to keep both sides equal and do operations to both sides and not one because then if you do an operation to only one side then you have changed the equation so it's important to do operations on both sides and that's an important rule to bare in mind.
2x + 33 + 3x + 20 = 113
→ Simplify
5x + 53 = 113
→ Minus 53 from both sides to isolate 5x
5x = 60
→ Divide both sides by 5 to isolate x
x = 12
But we are not finished, we have only found the value of x not the value of MON as we were asked so we have to substitute x back into the expression to find the value of MON
2x + 33
→ Substitute x = 12 back into the expression
2 × 12 + 33
→ Simplify
24 + 33 = 57
The value of MON is 57°
