The vertex angle of an isosceles triangle measures 42°. A base angle in the triangle has a measure given by (2x + 3)°. What is the value of x? What is the measure of each base angle?

The correct answer is:   [b]:   "physical systems" .

The answer would be  b. hope this !

Ithink the answer is ,temperature,pressure, and chemical changethey are identified by texture,streak,and locationthere are three ways that metamorphic rocks can form contact, regional,and dynamic metamorphism good luck, all this came right outta of the book

the answer is d. andesite. diorite and andesite have similar chemistries.

the other choices are wrong because:

basalt and gabbro have similar chemistries

granite and rhyolite have similar chemistries

pumice is just a rock that goes with no one

so the answer would be d. hope this
