Measure of angle C = 100°
Measure of angle A = 40°
We know, sum of all angles of a triangle is 180°.
Therefore, the measure of angle B

= [180 - (100 + 40)]° = 40°

When two angles of a triangle are equal, then the triangle is isosceles.
Here, the measure of angle A and B are equal, i.e., 40°
So, ∆ABC is an isosceles triangle.

Answers:

40°
Yes

Hope you could get an idea from here.

Step-by-step explanation:

If there are 10 skaters, it would go from 9, 8, 7, and so on...

So..

10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

= 3628800

A particle moves along the curve y=7 x 2+4y=7 x 2+4 in such a way that its xx-coordinate is changing at a rate of −5−5 centimete

ArbitrLikvidat [17]

Answer:

The y-coordinate is changing by the rate of -70 cm per sec.

Step-by-step explanation:

Given equation,

$y = 7x^2 + 4$

Differentiating with respect to time (t),

$\frac{dy}{dt}=14x \frac{dx}{dt}$

We have,

$\frac{dx}{dt}=-5\text{ cm per sec}, x = 1$

$\frac{dy}{dt} = 14(1)(-5)=-70\text{ cm per sec}$

What is the value of x in the equation, 70 = 12 + 9x – 2(x + 6)

lesantik [10]

<h3>Solution :-</h3>

➩ 70 = 12 + 9x - 2 ( x + 6 )

➩ 70 = 12 + 9x - 2x - 12

➩ 70 = 0 + 7x

➩ 70 = 7x

Here we can use 2 methods

Methods :-

Trial and error method :- By adding,subtracting , multiplying or dividing the same variable or constant on LHS & RHS
Transposing :- by transposing a term from LHS to RHS or RHS to LHS

• Trial and error

By dividing with 7 on both sides

➩ 70/7 = 7x/7

➩ x = 10

• Transposing

By transposing 7 from RHS. to LHS

➩ 70/7 = x

➩ x = 10

Hence , x = 10
