Answer:
Using the pythagoras theorem
Let's say the hypotenuse of the first diagram is b
b²=4²+2²
b²=16+4
b²=20
b=✔(20)
In finding x , b will be the opposite and the x be the hypotenuse
x²=(✔20)²+7²
x²=20 +49
x²=69
x=8.31
All triangles are unique.
The question should read, which two of the 4 given triangles are similar.<span>the intended answer is likely triangle D, because there are infinitely many different triangles described by D, namely all equilateral triangles.</span>
The answer is 9.
Hope I helped
To determine the nth term of sequence, first we need to know what type of sequence is it. It can be an arithmetic sequence or a geometric sequence. For an arithmetic sequence, the nth can be determined by the formula,
an = a1 + (n-1)d
For a geometric sequence,
an = a1r^n-1
Hope this answers the question.
Answer:
1/4 : 0.25
1.3 : 0.66
0.08
0.40
0.30
0.85
Greatest to smallest: 0.85>0.66>0.40>0.30>0.25>0.08
Smallest to greatest: 0.08<0.25<0.30<0.40<0.66<0.85
