using trigonometry:-

cos of angle ? = 7/16

so ? = arccos 7/16 = 64.06 degrees

The other angle is 90 - 64.06 = 25.94 degrees

Answer:

$JK=2.25\ units$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

$\frac{JK}{ST}=\frac{KL}{TU}$

substitute the given value and solve for JK

$\frac{JK}{1.5}=\frac{6}{4}$

$JK=(1.5)\frac{6}{4}$

$JK=2.25\ units$

Consider triangle ABC where AB=X+5, BC=X-2, area is 30cm squared. Find X by solving X^2+3X-70=0, and find the perimeter.

klasskru [66]

Answer:

What the hell AC is not given so you can't find the Perimeter

Step-by-step explanation:

x^2+3x-70=0

(x-7)(x+10)=0

x-7=0

x+10=0

x=-10

AB=x+5

AB=12

AB=-5

BC=x-2

BC=5

BC=-12

Area of ABC = 30cm2

Perimeter of ABC = AB+BC+AC
