Answer:
7,063
Step-by-step explanation:
90 × 78 + 53 − 20 ÷ 2 = 7,063
The answer is going to be 120
Answer:
Answer choices A, C, and D.
Step-by-step explanation:
If you assume that the 70 degrees is one of the base angles, then the other base angle is also 70 and the third angle is 40 degrees (thus answers C and D). However, if it is the top angle, the other two angles must both be 55 degrees (thus answer A). Hope this helps, and PM me with questions!
Let present age of women be x.
Then,Present age of her daughter be y.
According to the question,
<u>Two years ago,</u>
Woman age = x - 2
Her daughter age = y - 2
Woman was 7 times old as her daughter. [ Given ]
x - 2 = 7 ( y - 2 )
=> x - 2 = 7y - 14
=> x - 2 + 14 = 7y
=> x + 12 = 7y ....( i )
<u>A</u><u>f</u><u>t</u><u>e</u><u>r</u><u> </u><u>Three years </u>,
Woman age = x + 3
Her daughter age = y + 3
she would be 4 times old as the girl. [ Given ]
x + 3 = 4 ( y + 3 )
=> x + 3 = 4y + 12
=> x = 4y + 12 - 3
=> x = 4y + 9....( ii (
Now,
★ Putting the value of x = 4y + 9 from equation ( ii ) in equation ( i ),we get
x + 12 = 7y
=> 4y + 9 + 12 = 7y
=> 21 = 7y - 4y
=> 21 = 3y
=> 3y = 21
=> y = 21/3
=> y = 7
And,
x = 4y + 9
★ Putting the value of y in equation ( ii ), we get
x = 4 × 7 + 9
x = 28 + 9
x = 37
Hence, the present age of women is 37 years and her daughter age is 7.
Answer:16.97cm
Step-by-step explanation:
To find the hypotenuse side of an isosceles of side 12cm each
Using pythagoras theorem
hyp^2=opp^2+adj^2
hyp^2=12^2+12^2
Hyp^2=144+144
hyp=√288
Hyp=16.97cm
