the answer is 0.74 not 0.074
Step-by-step explanation:
<h3>7.4 <u><em>÷ </em></u><em> 10 = 0.74</em></h3>
X = 105
The circle is 360, so add the two numbers that are already present there together,. The rest two side are the same, so use 2x, x for one side, so two for two side.
85 + 65 + 2x = 360
150 + 2x = 360
2x = 210
x = 105
The answer is for 1st question is “10.4” and for the second question “non of these choices are correct”.
Explanation:
For the 1st question:
tan = opposite / adjacent
tan 30 = x / 18
18 tan 30 = x
x = 10.4
For the 2nd question,
If a triangle as an angle of 90 degree, it is 100% a right triangle.
Hope it helps :), mark me brainliest please!
Answer:
30 years
Step-by-step explanation:
Forming Algebraic expressions and solving them to find the age.
Ratio of age of mother and daughter = 5 : 3
Age of mother = 5x
Age of daughter = 3x
It is given that mother's age is 50 years.
⇒ 5x = 50
Divide both sides by 5.
x = 50÷5
x = 10
Daughter's age = 3x
= 3*10
= 30 years
