The ratio of the angles of a triangle is 3:7:2. What is the measure of the largest angle?

rewona [7]

Answer:

here's the solution,

let the given ratios as constants, by multiplying with same variable x

the angles will be 3x , 7x and 2x

now, we know the sum of the given angles measures 180°, since the sum of measures of all interior angles of a triangle is 180°

=》3x + 7x + 2x = 180°

=》12x = 180°

=》x = 15°

so, the measures of each angle is :

3x = 15 × 3 = 45°

7x = 15 × 7 = 105°

2x = 15 × 2 = 30°

and now, we can observe that the largest angle is 105°

Find the area of the triangle im not sue how to do this best answer gets brainly

vovangra [49]

Given :

▪︎Length of height of this triangle = 16 cm

▪︎Length of base of this triangle = 4 cm

We know that :

$\color{hotpink}\tt \: area \: of \: a \: triangle \color{plum}= \frac{1}{2} \times base \times height$

Which means :

The area of this triangle :

$= \tt \frac{1}{2} \times 16 \times 4$

$=\tt \frac{1}{2} \times 64$

$= \tt \frac{64}{2}$

$\color{plum} =\tt\bold{ 32 \: {cm}^{2} }$

▪︎Therefore, <u>the area of this triangle = 32 sq.cm</u>

What is 4 3/4 + 7/8 showing all work

Mekhanik [1.2K]

$4 \frac{3}{4} + \frac{7}{8}$

Convert mixed numbers to improper fractions

$= \frac{19}{4} + \frac{7}{8}$

Find de LCD for 4 and 8 :

Factor each denominator into its primes:

$4 = 2^2
$

$8 = 2^3$

Find the least common denominator $2^3 = 8$

Adjust fractions based on the LCD :

$\frac{19*2}{8} + \frac{7}{8}$

Since the denominators are equal , combine the fractions:

$\frac{2*19+7}{8}$

$\frac{38+7}{8}$

$= \frac{45}{8}$

Therefore:

Convert improper fractions to mixed numbers

$= 5 \frac{5}{8}$

hope this helps!
