Answer:

∠CAB = 20°

Step-by-step explanation:

Looking at the diagram, we can see that ADC is a straight line so it is a 180°. Using this information, we can find the ∠CDE :

∠CDE = 180° - ∠ADE

= 180° - 130°

= 50°

Triangle CDE is an isosceles triangle so ∠CDE = ∠CED = 50° and now, we can find the angle of C :

∠C = 180° - ∠CDE - ∠CED (angle in a triangle is 180°)

= 180° - 50° - 50°

= 80°

Given that triangle ABC is also an isosceles triangle so ∠C = ∠B = 80° and lastly, we can find ∠CAB :

∠CAB = 180° - ∠C - ∠B

= 180° - 80° - 80°

= 20°

An automobile engineer is redesigning a conical chamber that was originally specified to be 12 inches long with a circular base
kirill115 [55]

Answer:

the original volume is lesser than the new volume by 242.47 in³

Step-by-step explanation:

Volume of a cone is;

V = ⅓πr²h

Where;

r is radius

h is height

For the original chamber;

r = 5.7/2 = 2.85 inches

h = 12 inches

Volume of this original chamber is;

V_orig = ⅓ × π × 2.85² × 12

V_orig = 102.02 in³

In the new design, the chamber is scaled by a factor of 1.5.

Thus;

r_new = 2.85 × 1.5 = 4.275 inches

h_new = 12 × 1.5 = 18 inches

V_new = ⅓ × π × 4.275² × 18

V_new = 344.49 inch³

V_new - V_orig = 344.49 - 102.02 =

Thus, the original volume is lesser than the new volume by 242.47 in³

Solve the problems<br><br> A) X/840 = 1/21<br><br> B) 14/X = 16/20
Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

A) x/840=1/21

x=(1/21)*840=840/21=40

x=40

------------------

B) 14/x=16/20

simplify 16/20 into 4/5

14/x=4/5

x=14/(4/5)=(14/1)(5/4)=70/4

simplify

x=35/2
