Step-by-step explanation:
14.
by pythagoras,s theorem
15.
first perpendicular=y(say)
and second perpendicular=z (say)
y²=9²+7²=81+49=130
z²=y²+5²=130+25=155
x²=z²+4²=155+16=171
x=√(171)
Answer:
x=924
Step-by-step explanation:
348 + 926 = x + 350
we have two 2-terms additions in both sides of the equation.
348 and 350 are two <em>similar</em> numbers then x and 926 should be really <em>close</em> numbers.
(due to commutative property of additions 348 + 926 = 350 + x)
<em>since 348 has two units less than 350, then 926 must have two units more than x, and <u>x=924</u></em>
(indirect proportionality)
1. The three dots at the end of the number is called an ellipsis.
2. Since it doesn't terminate or repeat, the number is an irrational number.
3. When it can be written as a ratio, it is a rational number.
4. The decimal digits infinitely repeating is called a repeating decimal.
5. Ending decimal is another word for terminating decimal.
6. The fraction bar in which has numerator above and denominator below is a vinculum. Hope this helps!
