Answer:

15 inches of ribbon is needed.

Step-by-step explanation:

To find how much ribbon is needed to go around the edge of the card, find the perimeter. The perimeter is the length around the card.

Perimeter is found by P = 2l + 2w where w=3.5 and l=4.

P = 2(4) + 2(3.5)

P = 8 + 7

P = 15 inches

15 inches of ribbon is needed.

Use the law of cosines.
a2+b2−2abcosC=c2

Find the measure of angle C. It is the opposite side of c.
c2−a2−b2−2ab=cosC
cosC=13.62−22.52−182−2(22.5)(18)≈0.797
C=cos−10.797=0.649 rad=37.19∘

angle B:
a2+c2−2accosB=b2
cosB=b2−a2−c2−2ac
B=cos−1b2−a2−c2−2ac=cos−1182−22.52−13.62−2(22.5)(13.6)≈0.927 rad=53.13∘

angle A:
b2+c2−2bccosA=a2
A=89.68∘

Angles α and β are the two acute angles in a right triangle. Use the relationship between sine and cosine to find the value of α
8_murik_8 [283]

Answer:

The value of angle α is 18 degree.

Step-by-step explanation:

Given information: Angles α and β are the two acute angles , α < β.

Given equation is

\sin (2x-8)=\cos (6x-6)

\cos (90-(2x-8))=\cos (6x-6)        [\because \sin (90-x)=\cos x]

Equating both sides.

90-2x+8=6x-6

98+6=6x+2x

104=8x

13=x

The value of x is 13.

The measure of angles is

2x-8=2(13)-8=18

6x-6=6(13)-6=72

Since 18<72, therefore the value of angle α is 18 degree.
