Answer:

x = 61°

Step-by-step explanation:

since the triangle has 2 congruent sides then it is isosceles with the 2 base angle being congruent, both x°

the sum of the 3 angles in the triangle = 180° , then

x + x + 58° = 180°

2x + 58° = 180° ( subtract 58° from both sides )

2x = 122° ( divide both sides by 2 )

x = 61°

-3v-2=-2-8v+5v How many solutions? Will mark brainlest

Jet001 [13]

Answer:

infinite solutions

Step-by-step explanation:

-3v-2=-2-8v+5v

Combine like terms

-3v-2 = -2 -3v

Add 3v to each side

-3v-2+3v = -2 -3v+3v

-2 = -2

Since this is always a true statement, there are infinite solutions

How do I solve the equation (x+3)^1/2-1=x

konstantin123 [22]

Answer:

Step-by-step explanation:

$(x+3)^{\frac{1}{2} } -1=x\\(x+3)^{\frac{1}{2} } =x+1\\squaring\\x+3=x^2+2x+1\\\\x^{2} +2x-x+1-3=0\\x^2+x-2=0\\x^2+2x-x-2=0\\x(x+2)-1(x+2)=0\\(x+2)(x-1)=0\\x=-2,1$
