❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

a )

Sum of the interior angles of any triangle equals 180° .

Thus :

angle \: A + angle \: B + angle \: C = 180° \\

35° + 3(x+2)° + 52° = 180°

35° + 3x + 6° + 52° = 180°

3x + 93° = 180°

Subtract sides 93°

3x + 93° - 93° = 180° - 93°

3x = 87°

Divide sides by 3

\frac{3x}{3} =  \frac{87}{3}  \\

x = 29°

________________________________

b )

angle  \: C = 3 ( x + 2 ) °

angle \:  C = 3 ( 29+ 2 ) °

angle  \: C = 3 ( 31 ) °

angle  \: C =93 °

r : the common ratio  

A1 ; the first term

When a plant does not get enough water, the turgor pressure inside of the cells?
vivado [14]
Vacuoles are storage bins that are kinda like storage bubbles in plants and animal cells and turgor pressure happens when the water inside the plant cell vacuole starts to expand which pushes the cell memebrance or walls so when a plant doesn't get enough of water the plant will wilt which means the plant ends up losing it turgor pressure as well.
