Answer:
OK So i didnt know if it was +16.9 so the first answer i got i didn't add the 16.9 and i got z= -7.584 then when i did it with the 16.9 i got z= -21.104
Step-by-step explanation:
Answer:
Z=3
Step-by-step explanation:
z+12=15
z=3
Option D:
Right triangle
Solution:
Let us first define obtuse, acute right triangle and supplementary.
<u>Obtuse angled triangle:</u>
If any one of the angle in the triangle is more than 90°, then the triangle is an obtuse angled triangle.
<u>Acute angled triangle:</u>
If all the angles of the triangle are less than 90°, then the triangle is an acute angled triangle.
<u>Right angled triangle:</u>
If any one of the angle in the triangle is exactly 90°, then the triangle is a right angled triangle.
<u>Supplementary:</u>
If sum of the angles is 180°, then the angles are supplementary angles.
But this is not a kind of triangle.
In given triangle one of the angle is 90°.
Therefore, this is a kind of right triangle.
Option D is the correct answer.
Answer:
A) 4
B) Mode is 5
C) 10.5
Step-by-step explanation:
A) 62+x/12
(62 + x) ÷ 12 = 5.5 ×12
62 + x = 66
×= 66-62
×=4
B) mode is the highest occuring no which is 5
C) mean has been given as 5.5; mean plus mode= 10.5
Answer:
sin theta
Step-by-step explanation:
sqrt(1 - cos theta)(1 + cos theta)
=sqrt(1 - cos^2 theta)
=sqrt sin^2 theta
=sin theta
