For the ones with x, add up both expressions and set them equal to 90° and solve for x. For the ones with the missing angles, do 90-(given angle) = missing angle

This is geometry please help

EastWind [94]

Answer:

x = 31°

Step-by-step explanation:

$\triangle ABC \cong \triangle DCE... (given) \\\\\therefore m\angle B = m\angle E..(cact)\\\\\because m\angle B = 61\degree \\\\\therefore m\angle E = 61\degree \\\\In \: \triangle DCE\\\\m\angle D+ m\angle C + m\angle E = 180\degree \\(by \: interior \: angle \: sum \: property \: of \: a triangle) \\\\2x\degree + 57\degree + 61\degree= 180\degree \\\\2x\degree + 118\degree = 180\degree \\\\2x\degree = 180\degree - 118\degree \\\\2x\degree = 62\degree \\\\x = \frac{62\degree}{2} \\\\x = 31\degree$

Answer:

Step-by-step explanation:

Angles around a point add up to 360

x + 53 + 37 + 139 = 360

x + 229 = 360

x = 360 - 229

x = 131

7x²=28 I'm not sure about how to do thus problem

OverLord2011 [107]

$7x^{2} = 28$

$x^{2} = \frac{28}{7}$

$\frac{28}{7} = 4$

$x^{2} = 4$

$x = 2$ or $x = -2$
