Mathematics
1 answer:
Reptile [31]3 years ago
7 0

Answer:

Step-by-step explanation:

y=x+7.........(1)

y=3x+5.......(2)

Equating the two equations

3x +5 = x + 7

3x -x = 7 - 5

2x = 2

x = 2/2

x = 1

Putting x = 1 in (1)

y = x + 7

y = 1 + 7

y = 8

I need help with this <br> if you know the answer plz tell meh
uranmaximum [27]

Answer: from top to bottom: 115, 45, 115, 110, 115

Step-by-step explanation: 115 because the remain angle in that triangle is 65. 180-65 is 115. 45 because vertical angles are equal. 115 because 180-65 is 115. 110 because vertical angles are equal. 115 because vertical angles are equal.

3, 4, 5, 7, 9, 10, 2, 8<br><br> Mean__<br> Median__<br> Range__
Fudgin [204]

Answer:

Mean: 6

Median: 6

Range: 8

Step-by-step explanation:

Mean is found by adding up all the values in the set and dividing by the amount of numbers in the set (in this one there are 8) 2+3+4+5+7+8+9+10=48. 48 divided by 8 = 6.

Median is the number in the middle, when the numbers in the set are ordered from least to greatest. Since there are two middle numbers in this set we add them together and divide by 2. 5+7=12. 12 divided by 2 = 6.

Range is found by taking the largest number and subtracting the smallest number from it. 10-2=8.

An isosceles triangle ABC with the base BC is inscribed into a circle. Find the measure of angles of it, if measure of arc BC=10
zzz [600]

Answer:

The measures of the angles of ΔABC are

m∠A = 51° , m∠B = 64.5 , m∠C = 64.5°

Step-by-step explanation:

* Lets revise some facts in the circle

- The measure of the circle is 360°

- Equal chords intercept equal arcs

- The measure of an inscribed angle equals half the measure

 of the intercepted arc

* Lets solve the problem

- ΔABC is isosceles withe base BC

∴ AB = AC

- The vertex angle is A

∵ ∠A is an inscribed angle subtended by arc BC

∴ m∠A = 1/2 the measure of arc BC

∵ The measure of arc BC = 102° ⇒ given

∴ m∠A = 1/2(102) = 51°

- In ΔABC

∵ AB = AC ⇒ proved

∴ m∠B = m∠C ⇒ base angles of isosceles Δ

- The sum of the interior angles in any Δ = 180°

∵ m∠A = 51 ⇒ proved

∴ m∠B = m∠C = (180 - 51) ÷ 2 = 129 ÷ 2 = 64.5°

* The measures of the angles of ΔABC are

  m∠A = 51° , m∠B = 64.5° , m∠C = 64.5°
