What is the value of y? Y Y 60 O A. 120° B. 60° C. 40° O D. 30°

Grace [21]

Answer:

B. 60°

Step-by-step explanation:

1. The measure of all angles in a triangle sum up to 180°. This means that y + y + 60 = 120.

2. (Solving)

Step 1: Simplify both sides of the equation.

$(y+y)+(60)=180$
$2y + 60 = 180$

Step 2: Subtract 60 from both sides.

$2y + 60 - 60 = 180 - 60$
$2y = 120$

Step 3: Divide both sides by 2.

$\frac{2y}{2}=\frac{120}{2}$
$y = 60$

Step 4: Check if solution is correct.

$(60)+(60)+60 = 180$
$120 + 60 = 180$
$180 = 180$

Therefore, the answer is B. 60°.

The sum of the measures of two complementary angles exceeds the difference of their measure by 86_. Find the measure of each ang

Bad White [126]

As the sum of two complementary angles = a + b = 90 degree -------(1)

Difference of two complementary angles = a – b

According to question;

The difference of two complementary angles exceed the sume (90) by 86.

a – b = 90 – 86 = 4 -------(2)

adding equation (1) and (2);

2a = 90 + 4 = 94

a = 94 / 2 = 47

putting a = 47 in equation (1);

47 + b = 90

b = 90 – 47 = 43

So angle a = 47 and angle b = 43
