Answer:

6 units²

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A = \frac{1}{2} bh ( b is the base and h the height )

here b = DE = 3 units and

h is the distance from the vertex F to DE = 4 units, hence

A = \frac{1}{2} × 3 × 4 = 6 units²

1. B she started with 36 photographs,
22 = b - 18 + 13 - 9
b = 22 + 18 - 13 + 9
b = 36

I translated it into an equation, so I would say C, but since B is the only one with the right answer...

78 - 5 = 73
73 × 365 = 26645

The perpendicular bisectors of sides AC and BC of △ABC intersect side AB
tiny-mole [99]

The measure of ∠ACB will be 110°

<u><em>Explanation</em></u>

According to the diagram below, DE and DF are the perpendicular bisectors of AC and BC respectively and they intersect side AB at points P and Q respectively.

So, AE=CE and CF= BF

Now, <u>according to the SAS postulate</u>, ΔAPE and ΔCPE are congruent each other. Also, ΔCFQ and ΔBFQ are congruent to each other.

That means, ∠PCE = ∠PAE  and ∠FCQ = ∠FBQ

As ∠CPQ = 78° , so  ∠PCE + ∠PAE = 78°  or,  ∠PCE = \frac{78}{2}= 39°                                    and as ∠CQP = 62° , so ∠FCQ + ∠FBQ = 62° or, ∠FCQ = \frac{62}{2}=31°

Now, in triangle CPQ,  ∠PCQ = 180°-(78° + 62°) = 180° - 140° = 40°

Thus, ∠ACB = ∠PCE + ∠PCQ + ∠FCQ = 39° + 40° + 31° = 110°
