Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of angle ADB
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle ADB
Triangle ADB is an equilateral triangle (has three equal interior angles and three equal sides)
step 2
Find the measure of the angle CBD
we know that
An isosceles triangle has two equal sides and two equal angles
In this problem triangle BDC is an isosceles triangle
Because
AB=BC ---> given problem
AB=BD ---> by equilateral triangle
BD=BC ----> by transitivity
therefore
we have
so
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle BDC
substitute the given values
Answer:
y=33
Step-by-step explanation:
substitute -4 in the equation to get y
so (-4)x(-6)+9=33
(1.5 × 10 - 7) × (3.6 × 1015) ÷ (1.2× 10 - 3) = 3248
Step-by-step explanation:
The order of operations to solve a problem is:
- Brackets
- Exponents
- Multiplication or division
- Addition or subtraction
The problem is:
(1.5 × 10 - 7) × (3.6 × 1015) ÷ (1.2× 10 - 3)
At first solve the operations inside all the brackets
In the bracket 1.5 × 10 - 7 we must make multiplication at first then subtract
∵ 1.5 × 10 = 15
∵ 15 - 7 = 8
∴ (1.5 × 10 - 7) = 8
In the bracket 3.6 × 1015
∵ 3.6 × 1015= 3654
∴ (3.6 × 1015) = 3654
In the bracket 1.2 × 10 - 3 we must make multiplication at first then subtract
∵ 1.2 × 10 = 12
∵ 12 - 3 = 9
∴ (1.2 × 10 - 3) = 9
Now replace all the brackets by their answers
∴ (1.5 × 10 - 7) × (3.6 × 1015) ÷ (1.2× 10 - 3) = 8 × 3654 ÷ 9
- From the ordered above multiply at first then divide
∵ 8 × 3654 = 29232
∵ 29232 ÷ 9 = 3248
(1.5 × 10 - 7) × (3.6 × 1015) ÷ (1.2× 10 - 3) = 3248
