How to solve for area of triangle where A=67 degrees, b=11yd, and c=24yd

skad [1K]

Use the formula of an area of a tringle:

$A=\dfrac{1}{2}bc\sin A$

We have b = 11 yd, c = 24 yd and m∠A = 67°

$A=\dfrac{1}{2}(11)(24)\sin67^o$

$\sin67^o\approx0.9205\\\A=(11)(12)(0.9205)=121.506\ yd^2$

Bonnie is four years older than Clyde.

Doss [256]

Answer:

Bonnie's age is 18

Step-by-step explanation:

Let

x ----> Bonnie's age

y ---> Clyde's age

we know that

$x=y+4$ ----> equation A

$x-10=2(y-10)$

$x-10=2y-20$

$x=2y-20+10$

$x=2y-10$ ----> equation B

substitute equation A in equation B

$y+4=2y-10$

Solve for y

$2y-y=4+10$

$y=14$

<em>Find the value of x</em>

$x=14+4=18$

therefore

Bonnie's age is 18

Clyde's age is 14
