Proof:-
In ∆XYZ and ∆VWZ
Hence
∆XYZ∆VWZ(Side-Angle-Side)
Answer:
17) h=I(1-cosθ); 18) h=1.404.
Step-by-step explanation:
17) h=I-BC;
In ΔABC: m(∠C)=90°, m(∠B)=θ, AB=I, then BC=AB*cos(∠B); ⇒ BC=Icosθ;
Then h=I-Icosθ or h=<u>I(1-cosθ)</u>.
18) if I=6 and θ=40°, then h=6(1-cos40°)≈6*(1-0.766)=<u>1.404</u>, where cos40°≈0.766.

Answer: 1 1/2 or 1.5 yards of the garden will be planted with tomatoes.
Step-by-step explanation: First lets find the area f the garden by multiplying length x width.
7 1/2 x 1 = 7 1/2 yard
Now, we need to find what number is 1/5 of 7 1/2.
First convert the fractions to decimals to make it easier. 1/5 as a decimal is .2 and 7 1/2 as a decimal is 7.5.
Simply multiply .2 x 7.5 to get the amount of square yards planted with tomatoes.
.2 x 7.5 = 1.5.
So 1 1/2 or 1.5 yards of the garden will be planted with tomatoes.
Step-by-step explanation:
Adjacent sides of a square and a rectangle are always perpendicular to each other. Sides of the right-angled triangle enclosing the right angle are perpendicular to each other.
