How do i find x and y?

Solution,

We know ,

AB = AC

<B = <C

< A + <B + <C = 180° ( sum of angle in triangle)

or, 46 + y + y = 180°

or, 46 + 2y = 180°

or, 2y = 180° - 46°

or, 2y = 134

or, y = 134/2

y = 67°

The value of y is 67°

Now, In ∆ ABD

<BAD + <B + < ADB = 180°

or, 23 + 67 + X = 180°

or, 90 + X = 180

or, X = 180 - 90

X = 90°

The value of X is 90°

Hope this helps ...

Good luck on your assignment...

step-by-step explanation:

you can not divide by 0 so 4 ÷ 0 would be 0

0 × 9999 =0

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
