In trapezoid ABCD, AB ∥ CD , m∠A=90°, AD=8 in, DC=9 in, CB=10 in, and ∠B is acute. Find DB.
kiruha [24]

Answer:

the length of DB is 17 in

Step-by-step explanation:

Consider the sketch attached.

We will draw an imaginary line from point C to met line AB at point E.

A right-angled triangle will now be formed between points CBE.

The dimensions of the right-angled triangle will be:

CB = 10 in

CE= 8 in

EB = unknown

We will now proceed to find out the length of side EB using the Pythagoras' theorem.

EB =\sqrt{CB^2 -CE^2} \\EB =\sqrt{10^2 -8^2} \\EB = 6 in

From the shape, we can find out that another right-angled triangle is made between points DAB.

The dimensions of the triangle are:

DA= 8in

AB = 9 in + 6 in = 15 in

DB = unknown.

We will now proceed to find out the length of side DB using the Pythagoras' theorem.

DB =\sqrt{AD^2 +AB^2} \\DB =\sqrt{8^2 +15^2} \\DB = 17 in

Therefore, the length of DB is 17 in

48=16-0.5x
add 0.5 both sides
0.5x+48=16
mnus 48 boh sides
0.5x=-32
times 2 both sides

Solve the equation (x-4)(2x+3) = 4​
Marina CMI [18]

Answer:

(x-4.34)(x+1.84)=0

Step-by-step explanation:

2x^2 -5x-16=0

delta=

25  + 4 \times 2 \times 16  = 153

x1,2=

(5 +  \sqrt{153} ) \div 4 = 4.34  \\ (5 -  \sqrt{153} ) \div 4 =  - 1 .84
