Answer:

855.8

Step-by-step explanation:

hundreds tens ones . tenths hundredths thousandths

8 5 5 . 7 8 8

We are rounding to the nearest tenth, so we look at the next number which is 8. 8>= 5 so we will round the 7 up

855.788 rounds to 855.8

suppose a triangle has two sides of length 42 and 35 and that the angle.between these two sides is 120° what is the length of th

pickupchik [31]

Answer:

The length of the third side of the triangle is $7\sqrt{91}\ units$

Step-by-step explanation:

Let

c ----> the length of the third side of the triangle

we know that

Applying the law of cosines

$c^2=a^2+b^2-2(a)(b)cos(C)$

we have

$a=42\ units\\b=35\ units\\C=120^o$

substitute the given values

$c^2=42^2+35^2-2(42)(35)cos(120^o)$

$c^2=2,989-2,940cos(120^o)$

$c^2=4,459\\c=\sqrt{4,459}\ units\\c=7\sqrt{91}\ units$

The perpendicular bisectors of sides AC and BC of △ABC intersect side AB

tiny-mole [99]

The measure of ∠ACB will be 110°

Explanation

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, according to the $SAS$ postulate, 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°
