Answer:

C. 63 degrees

Step-by-step explanation:

When 2 triangles are congruent, no matter what postulate they are congruent by, all their sides and angles will be congruent.

We know that triangle ABC is congruent to triangle DEF. Their angles and sides are congruent and corresponding.

We know that angle A is 70 degrees, angle B is 47 degrees and angle C is 63 degrees.

Angle C and angle F correspond. Therefore, angle C and angle F are congruent. Angle C is 63 degrees, therefore angle F must be 63 degrees.

C. 63 degrees is the correct answer.

<u>Answer:</u>

• Equation = $2(\frac{7}{4}w + w) = 176$

• length = 56 ft

• width = 32 ft

<u>Step-by-step explanation:</u>

The ratio of the length to width is 7:4.

∴ $\frac{l}{w} = \frac{7}{4}$

⇒ $l = \frac{7}{4} w$ [Equation 1]

We know that the perimeter of the garden is 176 feet.

∴ $2(l + w) = 176$

⇒ $2(\frac{7}{4}w + w) = 176$

⇒ $\frac{7}{4} w + w = 88$ [From Equation 1]

⇒ $\frac{7 w + 4w}{4} = 88$

⇒ $\frac{11w}{4} = 88$

⇒ $11w = 352$

⇒ $w = \bf 32 \space\ ft$

We know from Equation 1 that:

$l = \frac{7}{4} w$

∴ $l = \frac{7}{4} (32)$

⇒ $l = \bf 56 \space\ ft$
