Answer:

11) tan(7x+3) = OE/OJ

7x+3=arctan(OE/OJ)=45

x=6


12) a) x = 40

<ajq = <acq (base angles of isosceles triangle)

50+x+90=180

x=40


b) they are congruent triangle, reason HL   (hypotenuse, leg)

aj=ac

aq=qa

right angle equal

Would this be correct? I simplified x to 8x.
Arte-miy333 [17]

\sqrt[3]{8x^3}\implies \sqrt[3]{2^3x^3}\implies \sqrt[3]{(2x)^3}\implies 2x~\hfill y=\stackrel{m}{2} x\stackrel{b}{+8} \\\\[-0.35em] ~\dotfill\\\\ \boxed{A}\qquad m = 2\\\\ \boxed{B}\qquad b = 8\\\\ \boxed{C}\qquad 0=2x+8\implies -8=2x\implies \stackrel{~\hfill y-intercept}{\cfrac{-8}{2}=x\implies -4=x}

A whistle is made of a square tube with a notch cut in its edge, into which a baffle is brazed. Determine the dimensions d and θ
jasenka [17]

Answer:

d = 7.51 cm

θ = 60°

Step-by-step explanation:

The baffle used in the notch of a whistle is a triangular baffle (Isosceles triangle OAB).

For the isosceles triangle, the sides with equal dimension are OA and OB which is represented with d

d = the vertical component of the side of a triangle

It is given by

6.5cm = d sin60

d = 6.5/sin60

d = 7.505553499465134

d = 7.51 cm -------- Approximated

To calculate angle θ

Angle on a straight line is = 180

So, 60 + 60 + θ = 180

θ= 180 - 120

θ = 60°
