Well 3 3/8 as a decimal is 3.375 and 1 5/6 as a decimal is 1.8333333333 and if you add those its <span>5.208333333</span>.
Answer:
14.1 =x
Step-by-step explanation:
Since this is right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin 42 = x /21
21 sin 42 = x
14.05174273 =x
Rounding to the nearest tenth
14.1 =x
Answer:
answer 2
Step-by-step explanation:
Answer:
9.64ft
Step-by-step explanation:
Since the diagram tends to form...a right angled triangle....;
with PR = 17ft...,PQ = 14ft
then to calculate the length of QR
we use the pythagoras theorem...which is only applicable to right angled triangles
PR^2 = PQ^2 + QR^2
(17)^2 = (14)^2 + QR^2
where we make QR the subject of formula;
QR^2 = (17)^2 - (14)^2
QR = square root of( 289 - 196)
QR = square root of( 93)
;Therefore the length of QR = 9.64ft
