Answer:
x= -74 or -84
Step-by-step explanation:
x^2+3x+37=-7x
x^2+3x+7x+37=0
x^2+10x+37=0
this convert to following
-b= -(10), a= 1, c =37
according to that
x= -74 or x= -84
Answer:
sine A = four-fifths
Step-by-step explanation:
You have a rectangle triangle ABC with hypotenuse AB 35, side CB 28 and side CA 21. The angle C is 90°.
In order to calculate sin A, you take into account that:
The opposite side to angle A is side CB = 28
Hypotenuse = 35
You replace the numeric values of the hypotenuse and side BC in the formula for sinA:
In order to simply the fraction, you divide both numerator and denominator by 7:
hence, the answer is
sine A = four-fifths
