Answer:
Step-by-step explanation:
m=10
Step-by-step explanation:
The angles ∠LHM and ∠JHM are on a straight line, therefore they are supplementary and add to 180 degrees
∠LHM+∠JHM=180
We know that ∠LHM is 2m+10 and ∠JHM is 5m+100, so we can substitute them in
2m+10+5m+100=180
Combine like terms
(2m+5m)+(10+100)=180
7m+110=180
Subtract 110 from both side s
7m=70
Divide by 7 on both sides
m=10
Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° = , cos45° = , thus
sin60° = = = ( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp =
Now consider the right triangle on the right, using the cosine ratio
cos45° = = = ( cross- multiply )
x = × = → C
When an equation is balanced, the different ways that the
simulation indicates are as follows:
- Happy Face appears
- The scales are balanced
- Pictures show same kind of atoms in reactants and products
- Pictures show same number of atoms in reactants and
products
Answer:
18. 2 times a number p squared
19. 3 times a number m to the power of 5
20. 1/2 plus 2
Step-by-step explanation:
Taking it from the left
f(x) = 2 for x <0
y = x for 0=< x < 3
f(x) = 3 for x>= 3
