In a triangle the second angle measures twice the first and the third angle measures 5 more than the second. If the sum of the a

Nostrana [21]

Answer:

Angle 1 = 35

Angle 2 = 70

Angle 3 = 75

Step-by-step explanation:

Let's define Angle 1 as x

Angle 1 = x

Angle 2 = 2x

Angle 3 = 2x + 5

x + 2x +2x + 5 = 180

5x + 5 = 180

5x = 175

x = 35

Angle 1 = 35

Angle 2 = 70

Angle 3 = 75

3. triangle abc has angle measures as shown (look at image).

mart [117]

Answer:

x = 6, ∠B = 50°

Step-by-step explanation:

a) 8x + 2 + 70 + 60 = 180

8x + 132 = 180

8x = 180 - 132 = 48

x = 48/8 = 6

b) ∠B = 180 - 70 - 60 = 50°

or 8x + 2 = 8*6 + 2 = 50°

A solution with a pH of 11 has a [H+] of $1.0\times 10^{-11}$

Option B is correct option.

Step-by-step explanation:

A solution with a pH of 11 has a [H+] of= ?

pH=?

Concentration of H+ [H+]= ?

Formula used: $pH=-log[H+]$

Putting values and finding [H+]

$pH=-log[H+]\\\,[H+]\,=10^{-pH}\\\,[H+]\,=10^{-11}\\\,[H+]\,=1.0\times 10^{-11}$

So, A solution with a pH of 11 has a [H+] of $1.0\times 10^{-11}$

Option B is correct option.
